The QuickTiter™ Lentivirus Titer Kit (Lentivirus-Associated HIV p24) provides a unique and more accurate way to measure physical lentiviral titer

This kit substantially minimizes the problem of overestimating lentiviral titer with traditional p24 ELISA kits. The traditional p24 ELISA detects both virus-associated p24 and free p24 generated by 293 cells during transient transfection. Free p24 can account for a substantial portion of total p24 in the supernatant. Therefore, the ELISA typically overestimates the quantity of lentivirus present
