Reversed-phase hplc assay for plasminogen activators |
abstract |
A process is described for monitoring the effectiveness of a purification process in removing plasminogen activator (PA) endogenous to Chinese hamster ovary (CHO) cells from a sample containing human tPA or variants thereof. This process comprises incubating the sample with a protease capable of specifically cleaving the Arg275 - IIe276 bond of human wild-type tPA and then with denaturing/reducing agents in respective amounts effective to reduce the disulfide bonds of human wild-type tPA; subjecting the sample to a reversed-phase high-performance liquid chromatography step, and analyzing the elution profile from the chromatography step for the amount of PA endogenous to the CHO cells present therein. |
