Information for Lentiviral Prep (Catalog # 141386-LV) ( Back to top )


Ready-to-use Lentiviral Prep particles produced from pLVX-EF1alpha-SARS-CoV-2-M-2xStrep-IRES-Puro (#141386). In addition to the viral particles, you will also receive purified pLVX-EF1alpha-SARS-CoV-2-M-2xStrep-IRES-Puro plasmid DNA.

Lentiviral particles carrying SARS-CoV-2 membrane (M) protein. This virus is used to make stable cell lines expressing the SARS-CoV-2 membrane protein.


  • Volume 1mL
  • Titer ≥ 1x10⁶ TU/mL
  • Pricing $100 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

Viral Quality Control

Titering Method:
  • ddPCR assay: 293T cells were transduced with serial dilutions of 141386-LV, harvested several days later, and genomic DNA was isolated. Copies of RRE were measured and normalized to RPP30.
  • PCR confirmation of insert: PCR was carried out on the viral preparation with primers targeting the pLenti backbone and the insert. The PCR product was visualized on an agarose gel for size confirmation.
