binding of soluble r-igg anti-bovine serum albumin ( bsa ) ic , prepared at molar antigen : antibody ( ag : ab ) ratio of 2:1 and 12:1 , showed quite different behaviour , the ic binding with association constants almost 10-fold lower than the affinity of monomeric r-igg , but binding six- to seven-fold as many igg molecules per cell at saturation .
