Information for Concentrated Lentiviral Prep (Catalog # 61425-LVC) ( Back to top )


Ready-to-use Concentrated Lentiviral Prep particles produced from lenti dCAS-VP64_Blast (#61425). In addition to the viral particles, you will also receive purified lenti dCAS-VP64_Blast plasmid DNA.


  • Volume 50 µL
  • Titer ≥1×10⁷ TU/mL
  • Pricing $150 USD for preparation of 50 µL 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 PBS
  • Selectable Marker Blasticidin
  • Purification Lentivirus was harvested from cell culture medium (DMEM + 10% FBS). Lentiviral particles were then collected by precipitation in polyethylene glycol (PEG) followed by centrifugation. Precipitated pellets containing viral particles were resuspended in PBS.


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:
  • Colony formation assay: A549 cells were transduced with serial dilutions of 61425-LVC and treated with blasticidin. Blasticidin-resistant colonies were expanded for approximately 2 weeks, stained with crystal violet, and counted. Read our colony formation titering assay protocol here.
  • Quality control was performed on this lentiviral preparation prior to concentration. Results and explanations of quality control methods can be seen below in the Information for Lentiviral Prep section.
