Purpose

Ready-to-use Lentiviral Prep particles produced from Fuw-dCas9-Dnmt3a_IM (#84478). In addition to the viral particles, you will also receive purified Fuw-dCas9-Dnmt3a_IM plasmid DNA.

Lentiviral particles carrying dCas9 fused with an inactive Dnmt3a catalytic domain (E664A, E756A)

Delivery

• Volume: .
• Titer: ≥5x10⁵ TU/mL
• Pricing: $100 USD for preparation of . virus + $30 USD for plasmid.
• Storage: Store at -80℃. Thaw just before use and keep on ice.
• Shipment: Viral particles are shipped frozen on dry ice. Plasmid DNA (≥ 200ng) will also be included in the shipment.

Viral Production & Use

• Packaging Plasmids: psPAX2 (plasmid #12260)
• Envelope: pMD2.G (plasmid #12259)
• Buffer: OptiPRO SFM
• Selectable Marker: None (Zeocin resistance is outside the LTRs and not transduced)

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

Titering Method:

• 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.

Notes:

• 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.
