Formulated as a 10X concentrate, this PBST buffer features 1% Tween‑20 for efficient and uniform washing during antibody‑based assays. The non‑ionic detergent assists in lowering background noise and preventing unwanted protein adsorption on membranes and plates. Its phosphate buffering system maintains consistent pH 7.4, ensuring stable assay conditions. Suitable for ELISA, immunofluorescence, and blotting workflows, this reagent provides clean, reproducible results across repeated washes.
