This 10X TBST solution combines Tris‑buffered saline with 0.5% Tween‑20, providing balanced ionic strength and detergent action for immunoassay procedures. Supporting a stable pH range of 7.4–8.0, it minimizes nonspecific binding without compromising antigen‑antibody interactions. Commonly employed as a wash or blocking buffer in Western blotting, in situ hybridization, and immunohistochemistry, it ensures low background and consistent signal intensity. TBST also performs effectively as a diluent for antibody and reagent preparations in molecular biology workflows.
