WebbPlace the antibody-protein A, G, A/G agarose mix on a shaker and rotate at 4°C for one hour. Spin down the protein A, G, A/G beads for two minutes at 5,000 rpm and wash the antibody-beads three times with cell lysis buffer. Preparation of cell extract: Collect cells and centrifuge at 1200 rpm for 5 minutes at 4°C. Webb15 juli 2014 · For each wash modifier, clearance of HCPs appeared to be independent of pH at low modifier concentrations (Figure 2). Washes with tetramethylammonium chloride (TMAC) or arginine appeared to be the most effective modifiers to break HCP–mAb1 interactions and reduce the levels of HCPs to ∼20% of control (Figure 2).
