WebbMonovalent Fab fragments can be used to “mask” or block the endogenous Ig epitopes, making them unavailable for detection by the labeled secondary antibody. Fab fragments have a single antigen binding site, so they will not capture the primary antibody used in a subsequent step. In contrast, whole molecule IgG and F (ab’)2 fragments are ... Webb16 nov. 2024 · For indirect IF, the primary antibody targets the antigen of interest but is not attached to a fluorescent molecule, instead a secondary antibody that targets the primary is conjugated to a fluorophore (Figure 1).
