PBS with Tween™ 20 (pH 7.4)

High Quality Molecular Biology Grade Buffer for a Reliable & Convenient use in a wide range of Applications

Phosphate-Buffered Saline with Tween™ 20 (PBS-T) is a high quality, reliable and convenient water-based salt solution ideal for use in sample preparation and as a wash buffer in general immunoassay applications.

It includes Tween 20, a non-ionic detergent additive that reduces non-specific binding and protein-protein interaction during the wash step in protein and immunoassay procedures such as ELISA and Western blotting. Decreasing the non-specific binding and staining makes ELISA results and blots easier to interpret.
