Viral Service: Lentivirus
Addgene's lentiviruses are made from plasmids that are currently in our repository. You can obtain the plasmid from us or receive a ready-to-use viral preparation from the inventory below.
Lentiviruses are distributed as purified viral particles in solution that are suitable for in vitro use. Volume and minimum titers are listed on each item's material page. Actual titers are reported with each shipment.
For more details about our viral service, visit our Viral Service landing page.

Cas9 viruses can be used to interrogate the genome in a variety of ways. Cas9 proteins can be guided to specific genomic sites by an RNA guide (gRNA) that harbors targeting sequences. Browse our repository for a list of gRNA plasmids targeting specific genes. For more information on CRISPR plasmids and function, see our CRISPR plasmids resource page.
