Impurity clearance
WitrynaIn addition to the impurity clearance study, we tested the ability of the optimized MAb A POROS HIC BE and FT processes to clear retrovirus XmuLV and parvovirus MVM. In the POROS Benzyl Ultra FT process, we observed complete clearance of XmuLV (>4 log) and minimal clearance of MVM (<1 log) up to 120 g/Lr load at 2-minute residence … Witrynaimpurity: [noun] something that is impure or makes something else impure.
