Viral Service: Lentivirus
We are offering ready-to-use viral preparations of several popular lentiviral plasmids and pooled libraries in our repository. With viral service, Addgene provides high-quality and high-titer viral preparations. We perform quality control experiments, including using our lentiviruses for stable cell line generation, colony formation titering assay, or fluorescence titering assay. You can see the results of our quality control experiments on the material pages for viral catalog items. For descriptions of Addgene's viral production protocols and quality controls, visit our viral production page. For protocols on how to use virus from Addgene or how to make your own virus, see our list of viral protocols with tips and sample data.
Addgene's lentiviruses are made from plasmids that are currently in our repository, so feel free to obtain the plasmid from us, or take advantage of our viral service by browsing our available lentiviruses below!
Each viral service request will also include virus associated DNA, which is a sample of the purified DNA from the original plasmid that was used to make the virus. In order for Addgene to provide viral services to you, we must ensure that you have the right to use the original plasmid. Distribution of the original plasmid is important because it is the actual material being referenced in the Material Transfer Agreement (MTA) and its inclusion is what gives you permission to use the plasmid.

Cas9 and CRISPR-activator Lentivirus
Cas9 viruses can be used to interrogate the genome in a variety of ways. To perform genome edits, Cas9 nuclease is used to generate double-stranded breaks (DSBs or cuts) or single-stranded breaks (nicks). When fused to a transcriptional repressor, catalytically-dead Cas9 mutants (dCas9) can interfere with and reduce transcription. Alternatively, dCas9 can be fused to a transactivator and used as a transcriptional activator. Finally, when fused to a fluorescent protein, dCas9 can be used to visualize genomic loci.
Browse our list of available Cas9 and CRISPR-activator lentiviruses based on their functions. Cas9 proteins can be guided to specific genomic sites by an RNA guide (gRNA) that harbors targeting sequences. See our list of experimentally validated gRNA viruses in viral format below or browse our repository for a list of validated gRNA plasmids.
