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.
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.
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.
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.
On this page, you can see a preview of the final plasmid page that will appear on the Addgene website once their plasmids are available online. Please check all information on this page to ensure it is correct. You can easily update information by navigating to previous pages using the links at the top of the page.
When you are satisfied with the plasmid information, click on the green "Save verified data and return to article" button to return to the table with all plasmids for this repository. You can enter the information for the next plasmids in your repository.
