Boston Bioproducts Inc Phosphate Buffered Saline-Tween, PBST (20X, with 1% Tween-20, pH 7.4) - 1L
Supplier: Boston Bioproducts Inc IBB171X1L
20X Phosphate Buffered Saline with Tween-20 (PBST) is a specialized variant of PBS, supplemented with Tween-20, a non-ionic surfactant. Tween-20 minimizes the non-specific binding and background noise, resuting in enhanced signal to noise ratio. PBST is often used in immunoassays such as ELISA and Western Blotting, where it serves as a washing and blocking buffer. With a stable buffering pH range between 7.0 and 7.4, PBST maintains ionic strength and protein solubility for biological assays.
