Addgene will create a custom webpage that lists all of the plasmids from your laboratory that are available for request. The URL will be in the format: www.addgene.org/PIfirstname_PIlastname . For example, see www.addgene.org/Robert_Weinberg/. You can either post your unique URL on your laboratory's website or email it to requesting scientists. (Note: Your plasmids will not be listed on your webpage until they have passed quality control and the MTAs have been approved.) Alternatively, if you know the specific plasmid that is being requested, you can refer the plasmid to another scientist by sending the URL using the format: www.addgene.org/Plasmid#. For example, see www.addgene.org/1764/.
