In Addgene it isour taskto facilitate the sharing of plasmids. To achieve this goal, we will archive all plasmids you deposit with us and distribute them to academic scientists and non-profit institutions around the world. Also, the deposit is free! When we travel to talk to scientists about how we can help them share plasmids, we get a lot of questions about how the deposit process works. To make things a little easier for you, we have written this post as a step by step guide to the online deposit process. To deposit plasmids online, you mustCreate an account with addgenebefore starting the process. After logging into your account, you can start the deposit process by clicking on "initial deposit” in the plasmids menu: As you can see, when you start depositing, you have three options: 1. You can "Send plasmids from a published article":This option allows you to quickly match your plasmids to the original publication in which you described them. Search your article like in PubMedand select the appropriate publication. This publication will appear at the top of the final plasmid pages and scientists are encouraged to cite this article when using their plasmids. 2. You can "submit pre-released or unreleased".PAGLasmide“: Addgene excited to sendprevious versionPlasmids so that they are available when the article is published.Plasmids can be linked to a peer-reviewed manuscript OR a preprint. In the case of preprint submissions, we will gladly update the publication information once the manuscript has been published in a peer-reviewed journal. To start this process, simply enter a general description of the plasmids or enter the title of your preprint and select the desired propagation status: 3. Submit plasmids using our table:The spreadsheet option is recommended for depositing 15 or more similar plasmids (eg gRNAs on the same backbone). Our table has columns corresponding to the plasmid data we need; You can copy and paste your information directly into the file. This file can be sent via email.deposit@addgene.orgalong with your GenBank files, plasmid sequences and/or maps. We can accept stream files in any format. After selecting your publication or entering your description, you can add plasmids to your article on the next page: On the item page, enter the name, type, and description of each plasmid associated with this deposit.as explained below:Enter item information

3. Description- indicate the cloned gene in your plasmid, any tags or fusion proteins contained in the plasmid, any mutations and the intended purpose of the plasmid.
After naming and describing all the plasmids in your repository, you need to click the "Enter data" button to start entering the plasmid details.
Enter plasmid information
As you go along, enter the plasmid data on the pages described below.
If you deposit pooled libraries or bacterial strains, pleasecontact us+1 (617)-225-9000.
You can complete these pages one by one by entering the appropriate data and clicking "Save and proceed to the next step" (green button at the end of the screenshots below), or you canClick the Save button andScroll through the different pages by clicking on the appropriate boxes at the top of the page.
Pro tip!
Be sure to click the blue "Save" button at the bottom of the page before moving to another page so you don't lose any data you entered.
1. Sequences, Maps and Files:
Provide complete or partial plasmid sequences and vector maps. The more string data available, the better. We strongly recommend that you load full sequence data whenever possible.Note that the complete plasmid sequence can be theoretically assembled or assembled, it does not need to be fully verified by sequencing.
Upload any support files that make it easier for scientists to get the most out of their plasmids (could be logs, GenBank files, etc.).
2. Gene and Insertion
*Note: This page is not displayed for empty backbones
Enter the name of any gene contained in your insert and the total size of the insert. You can select the species the gene or insertion sequence came from and provide the associated GenBank ID. Entering this information will populate a list of possible matches of the Entrez gene with your entry. Select the appropriate gene when it appears in the list of Entrez genes, as this will make it easier for other scientists to find information about your plasmid.
Pro tip!
In order for the Entrez gene list to be automatically populated with the correct gene, it is best to enter the full official NCBI gene name in the Gene/Enter field. After selecting the appropriate gene from the list, save your progress and modify the Gene/Insert and Alternative Name fields as needed.
Use the Relevant Mutations/Deletions field to describe any mutations in your entry using standard mutation notation. Give the amino acid change and the functional consequences of that change. For example, "Aspartate 123 mutated to lysine (D123K) decreases biosensor affinity for calcium".
Describe any tags or merges (e.g. His, FLAG,EGFP, etc.) in your add-in. Use the drop-down menu to specify whether the tag is on the N or C terminal and whether it was present on the backbone or was part of the insert (contained in the constraint sites used to clone the insert to the vector backbone).
As part of our quality control process, we will rate the characteristics you notice on this page.
3. Cloning information:
Enter the name of the vector backbone into which you cloned your insert and fill in the appropriate fields with the vector backbone manufacturer, the vector backbone size, the total size of your vector + insert, any changes made to the backbone, and the type icon did, off.
Pro tip!
See the Addgene ID in the Backbone Manufacturer field for backbones ordered through Addgene.
The vector type should describe how you intend to use your plasmid. For example, if your plasmid is designed so that you can produce large quantities of your insertE coli, so this is aBacterial ExpressionVector. If your plasmid fits into more than one category, check all applicable categories (e.g.,For a lentiviral vector for use in mammalian cells, cflentiviraisjmammal expression). This information makes it easier for scientists to find you.Rplasmid by type.
If your plasmid has an insert, you will be asked to indicate how you cloned the insert: the cloning method used, the restriction enzymes used (if applicable) andprimerwhich can be used to sequence after its insertion(type primer name and sequence directly into the box as shown below). This information will greatly facilitate Addgene's quality control processes and make it easier for scientists to use your plasmid.
Enter cloning information to describe how your gene was inserted into the plasmid backbone and which primers can be used to verify it, as shown below:
4. Growth and Expansion:
Show how Addgene and other scientists can propagate their plasmid. Accurate information greatly simplifies the deposit process and allows other researchers to access and use your plasmids sooner.
Whenever possible, we propagated plasmids in the DH5α cloning standard strain. Please indicate if your plasmid cannot be propagated on DH5α. For plasmids with highly repetitive sequences (which may be prone to recombination in bacteria), e.g.lentiviral,retroviral, jAAV-plasmid, we recommend theNEB stable voltage. For plasmids containing the ccdB gene, such asThe gateway vector, we recommend ccdB Survivalcepa.

FAQs
How do you add a gene to a plasmid? ›
Steps of DNA cloning
Cut open the plasmid and "paste" in the gene. This process relies on restriction enzymes (which cut DNA) and DNA ligase (which joins DNA). Insert the plasmid into bacteria. Use antibiotic selection to identify the bacteria that took up the plasmid.
Materials will be shipped as follows: Plasmids: shipped as bacterial stabs at room temperature; stable for approximately 2-3 weeks in transit. Pooled Libraries: shipped as tubes of liquid DNA on blue ice; viable for approximately 2-3 weeks in transit, even at room temperature.

Each plasmid created carries a $115 cost in materials excluding any restriction enzymes or vector purchases (see above). With the addition of the restriction enzyme and a vector purchase, the cost could go up by a few bucks, or a hundred, respectively just for reagents.
How long do plasmids last at? ›Plasmids provided as DNA, in suspension or on filter paper, should be stored at 4°C for up to two weeks.
How do you store plasmid DNA? ›Storing DNA: temperature and longevity
The most common solution is to keep your plasmid at -20°C or even at -80°C, in this case your preparation can be eluted in water or in your buffer of preference, and it will be stable for years.
Can I ship the plasmids at room temperature? Yes, if your plasmid is stored in a TE buffer, you can ship them to us at room temperature. Otherwise, we recommend using a cold package (blue or dry ice) for shipment, in order to reduce the likelihood of DNA degradation.
How do you send plasmid DNA? ›
To send plasmid DNA by mail: Spot 5 µl (0.1-1µg) of plasmid DNA onto sterile Whatman filter paper. Circle spot with pen or marker and let dry. Wrap filter paper in saran wrap and send out by regular mail.
How is plasmid DNA transferred? ›When a bacterium divides, all of the plasmids contained within the cell are copied such that each daughter cell receives a copy of each plasmid. Bacteria can also transfer plasmids to one another through a process called conjugation.
How long can plasmid DNA stay at room temperature? ›My results indicate that plasmid DNA can be shipped in either the liquid or dried form at room temperature, but that it should be recovered within 2–3 weeks, transformed, and amplified. The amplified plasmid DNA should be maintained at -20°C for long-term storage.
How much do Addgene plasmids cost? ›| Academic/ Nonprofit | Industry/For-Profit | |

| Price Per Plasmid | $75 USD | Starting at $200 USD* |
| Price Per Cloning Grade DNA Preparation | $95 USD | $220 USD |
For most orders, this typically takes 2-3 business days. Learn more about how to track your order status on our website. After your order has shipped, the order contact and recipient scientist will receive a confirmation email with a tracking number.
What are the methods of inserting the plasmid into the host cell? ›Physical methods such as electroporation or microinjection actually pokes holes in the cell membrane so DNA can be introduced directly into the cell. Microinjection requires the use of a fine needle to deliver nucleic acids to individual cells.
What are the two most common ways to insert genes into plants? ›The two conventional ways of transforming plants rely on the use of either the bacterial plant pathogen Agrobacterium tumefaciens or a particle gun to deliver the DNA to be inserted. These methods insert DNA at random sites in the plant genome.
How is a gene inserted into a GMO? ›For GM plants, the bacterium most frequently used is called Agrobacterium tumefaciens. The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells. The plant cells that have successfully taken up the DNA are then grown to create a new plant.
Can you insert plasmids into cells? ›Still, scientists have discovered many ways in which plasmids and other foreign DNA can be introduced to cells. Much like methods for bacteria, there are both chemical and physical methods of transfection produce transient holes in the cell membrane and get uptake of foreign DNA.
How do you know if a plasmid has a DNA insert? ›If the plasmid contains the insert, you will see two bands but if the plasmid doesn't, you will just see one band. These are only a few examples of how you can use restriction digest to screen your clones, but there are many other ways to choose restriction enzymes for this approach.
How is an insert prepared for cloning? ›
The source of the insert for cloning may be genomic DNA, a portion of another plasmid, or a linear DNA fragment. Regardless of the type of source DNA, a common first step in preparation of the insert is to perform restriction digestion to generate compatible ends for subsequent splicing into the vector.
What enzyme inserts a gene into a plasmid? ›Restriction enzymes and DNA ligase are often used to insert genes and other pieces of DNA into plasmids during DNA cloning.
How are genes inserted into plasmids quizlet? ›How are genes inserted into plasmids? through the action of restriction enzymes isolated from bacteria. Cutting two pieces of DNA with the same restriction enzyme allows what? Enzme is used to bond the gene permanently into the plasmid.
How to confirm if there is an insert in a plasmid without sequencing? ›For a simple way... take a vector specific primer with 3' end close to your insert and take another primer used to amplify your insert in such a way that you could get a amplification with PCR and done. If there is product from this PCR then you got your insert.
What are the two enzymes needed to make a recombinant plasmid? ›Recombinant DNA is the method of joining two or more DNA molecules to create a hybrid. The technology is made possible by two types of enzymes, restriction endonucleases and ligase.
How do genetic engineers insert recombinant plasmid into a host? ›After the foreign gene is inserted, another enzyme, called a ligase, is used to sew the plasmid together. Plasmids are ideal vectors for carrying the new gene into a host cell, because, in nature, plasmids are routinely passed from one bacterium to another, where they are readily accepted.
