WebJan 1, 2012 · The derivatized thiols are separated by reversed-phase HPLC and can be accurately quantified after method optimization. The estimated thiol content represents total amount of adducted forms present in the analyzed samples. The limit of quantification (LOQ) was established; specifically, the lowest amount of quantifiable cysteine adduction … WebQuantification (titer determination) of a lentivirus to ensure efficient expression is usually based on the quantification of the p24 protein. ELISA assay is the traditional method for lentiviral titer determination, aiming for this particular protein. However, this method measures virus-associated p24 along with possible
