Do I need to use Proteinase K in the CGT Viral Vector Lysis Kit? What is the recommended concentration?

No, Proteinase K use is optional and does not interfere with the kit performance. It is recommended to use 2 µL of Proteinase K (RP107B) in a 50 µL reaction. The Proteinase K has a concentration of 20mg/mL with 800 U/mL.
