PhosphoBlocker™ Blocking Reagent

• Superior blocking compared to dry milk or serum
• Enhances low level phosphoprotein signal without increasing background
• Preserves phosphoprotein antigens during Western blot procedures
• Easy-to-use premixed dry blend

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. Our PhosphoBLOCKER™ Blocking Reagent provides superior blocking by maximizing signal-to-noise ratio. The PhosphoBLOCKER™ reagent particluarly excels with very low levels of endogenous phopsphoproteins.
