Formulated at pH 7.6 and 10X strength, this Tris Buffered Saline with 0.5% Tween‑20 is optimized for experiments requiring slightly more alkaline conditions. Its non‑ionic detergent reduces background staining and nonspecific adsorption while preserving antigen binding during immunolabeling. TBST (7.4–8.0 range) provides reliable washing performance in Western blotting, immunocytochemistry, and hybridization methods, ensuring reproducible results across multiple assay platforms.
