Viral Production & Use
Biosafety
Requestor is responsible for compliance with their institution's biosafety regulations. Lentivirus is generally considered BSL-2. AAV is generally considered BSL-1, but may require BSL-2 handling depending on the insert. Biosafety Guide

Viral Quality Control
- Proviral Integration Assay: Lenti-X 293T cells were serially transduced with 84478-LV or a control virus of known titer. 72 hours after transduction cells were harvested, and gDNA extracted and assessed for integrated copies of WPRE.
- PCR confirmation of insert: PCR was carried out with primers targeting the dCas9 protein and WPRE. The PCR product was visualized on an agarose gel for size confirmation.
- Forward Primer: dCas9-fwd, ACCGTGTACAACGAGCTGAC
- Reverse Primer: WPRE-R, CATAGCGTAAAAGGAGCAACA
- Confirmation of protein expression: A549 cells were transduced with 84478-LV. 96 hours later, cells were fixed in 4% paraformaledyhyde and stained with 5 μg/mL anti-CRISPR Cas9 [7A9-3A3] (Abcam ab191468) primary antibody and Alexa Fluor 488 donkey anti-mouse IgG secondary antibody (ThermoFisher R37114). Nuclei were counterstained with DAPI. Cas9 expression was confirmed by fluorescence microscopy.
