Name: Phosphate Buffered Saline-Tween, PBST (20X, with 2% Tween-20, pH 7.4)
Brand: Boston BioProducts
SKU: IBB-170X-1L
Availability: InStock

Useful in cell culture, molecular biology, protein research, and purification
Often used as a wash buffer in immunoassays and protein purification
Ready-to-use once diluted to 1X working concentration

This concentrated 20X PBST solution with 2% Tween‑20 is designed for laboratories requiring adjustable detergent strength and extended reagent life. It provides exceptional control of nonspecific binding during antibody‑based detection, resulting in precise and low‑background signal development. The phosphate buffer component maintains consistent pH 7.4 and ionic strength, safeguarding protein conformation and solubility. Ideal for washing, blocking, and rinse steps in ELISA, Western blot, and other immunochemical protocols.
