PBST [10X]; Phosphate buffered saline with Tween-20; 80mM Na2HPO4, 1.5M NaCl, 20mM KH2PO4, 30mM KCl, 0.5% Tween-20, pH 7.4

Description

General Description

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.
