Successful Transduction Using Lentivirus - Sigma-Aldrich

After a lentivirus preparation is complete, the titer will need to be determined prior to transduction. Viral titers reported for our lentiviral products are determined by p24 ELISA. This assay measures lentivirus-associated p24 capsid protein. We determine the TU/mL based upon the p24 assay from ZeptoMetrix.
