Ready-to-use PBS buffer tablets with Tween®20 containing the non-ionic detergent Tween®20 which acts through blocking. It has the ability to reduce non-specific binding and protein-protein interaction during the wash step in protein and immunoassay procedures such as ELISA and Western blotting. By decreasing the non-specific binding and staining makes interpretation of ELISA results and Western blots easier.

Each tablet dissolved in deionized water yields a 0.14M sodium chloride 0.0027M potassium chloride, 0.05% Tween®20, 0.01M phosphate buffer with pH7.4 at 25°C. Final buffer volumes are: 100mL and 500mL (D2003 >) or 1L (D2004 >).
