PhosphoBlocker™ Blocking Reagent, Cell Biolabs

PhosphoBLOCKER™ Blocking Reagent provides superior blocking by maximizing signal-to-noise ratio

The PhosphoBLOCKER™ reagent is an easy-to-use premixed dry blend that enhances low level phosphoprotein signal without increasing background. The reagent particluarly excels with very low levels of endogenous phopsphoproteins.

Most commercially available Western blot blockers, such as dry milk or serum, are sufficient to block unreactive sites on the membrane. However, they are not designed to preserve phosphoprotein antigens during blotting.
