TBST is commonly used as a wash solution for Western blot membranes and microtiter plate wells in ELISA assays. The Tris 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.

Procedure:
Ready to use. 
1X Concentration is 10mM Tris.HCl, 15mM NaCl, 0.05% Tween 20 at pH7.5

Store at Room Temp.
