  • Titer ≥7x10⁵ TU/mL
  • Pricing $150 USD for preparation of 1mL 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
  • Selectable Marker Hygromycin

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:
  • ddPCR assay: 293T cells were transduced with serial dilutions of 61426-LV, harvested several days later, and genomic DNA was isolated. Copies of RRE were measured and normalized to RPP30.
Notes:
  • PCR confirmation of insert: PCR was carried out with primers targeting the hygromycin-resistance gene and pBluescript. The PCR product was visualized on an agarose gel for size confirmation.
    Forward Primer: Hygro-F GACGGCAATTTCGATGATG
    Reverse Primer: pBluescript-KS TCGAGGTCGACGGTATC

Addgene Comments

While the typical yield for lentiviral vectors ranges from 10⁶-10⁷ TU/mL, titers for large or toxic inserts, such as for MS2-P65-HSF1, can be 10-fold to 100-fold lower. Scientists generating their own lentiviral particles from MS2-P65-HSF1 should expect similarly low titers.

  • Confirmation of protein expression: A549 cells were singly transduced with 61426-LVC or doubly transduced with 61425-LV and 61426-LVC at an MOI of 1, and treated with hygromycin or hygromycin and blasticidin, respectively. Polyclonal pools of hygromycin-resistant or hygromycin and blasticidin-resistance cells were expanded, collected, lysed and tested for p65 expression via immunoblotting.
