10X Tris Buffered Saline with 0.5% Tween 20

10X Tris-buffered Saline (TBS) with 0.5% Tween 20 is used as a common western blot wash solution and general wash buffer in immunoassay applications. Tween 20, a non-ionic detergent, reduces non-specific binding and protein-protein interaction during the wash step in immunoassay procedures.
