WebThe secondary antibody may be binding to the blocking reagent. Add a mild detergent such as Tween 20 to the incubation and washing buffer. Note that phospho-specific antibodies may react with a milk blocking agent due to the presence of the phosphoprotein casein. If using phospho-specific antibodies, block with BSA instead of milk. WebDetergents can either be harsh (eg Triton™ X-100 or NP-40) to disrupt proteins, or mild (eg Tween 20 ®, saponin or digitonin) so as to not dissolve plasma membranes. Detergent permeabilization can significantly improve antibody access to antigens in the cytoplasm, on the cytoplasmic face of the plasma membrane, and soluble nuclear antigens.
