We preincubated HEK293F cells with (A) amiloride hydrochloride, an inhibitor of Na+/H+ exchanger activity, (B) bafilomycin A1, a specific and potent inhibitor of vacuolar H+ ATPase in early endosomes, (C) monensin, an inhibitor of both endosomal acidification and receptor recycling, and (D) dynasore, a potent and specific dynamin inhibitor (which is involved in clathrin- and caveolin-mediated endocytosis) in 5% MBL-deficient serum in the absence or presence of rhMBL at 37C for 1 hour
