Phosphate buffer saline 0.01 M pH 7.2 with Tween 20

Phosphate buffered saline (PBS) solution with the detergent Tween® 20 is a balanced salt solution and is one of the most commonly used buffers as a wash solution for Western blot membranes and microplate wells ELISA assays. The wash buffer with Tween® 20 is an optimal formulation of pH stabilizer, salts and detergents designed to remove excess material from wells of microplate or membranes without disrupting the binding reaction. It's very important to use a good washing buffer because it is able to separate bound and unbound reagents/serum component.

The Wash Buffer is offered as a 20x concentrated solution.
