Webreaction molar ratios result in fluorescein-antibody conjugates with F/P ratios of 1−2, 2−4 and 3−6, respectively. This procedure can be modified if a protein of a different molecular weight (or a different amount of IgG) is used in the labeling reaction. (See Table 2 reaction mixture ratios for whole IgG, IgM, or antibodyfragments.) 1.
