• A 10X Concentrated solution of Phosphate Buffered Saline with Tween® 20. The 10X Concentration is 80mM Na2HPO4, 1.5M NaCl, 20mM KH2PO4, 30mM KCl, 0.5% Tween® 20, pH 7.4.

 

  • PBST is commonly used as a wash solution for Western blot membranes and microtiter plate wells in ELISA assays. The Phosphate Buffered Saline with Tween® 20 is an optimal formulation of pH stabilizers, salts and detergents designed to effectively remove excess material from membranes and microtiter plate wells without disrupting the antigen/antibody binding reaction.

 

  • By maintaining the proper buffering environment, unbound components can be washed away without suppressing antigen-antibody binding interactions, thereby reducing nonspecific background and increasing the specific signal.
