Tween 2 and Phosphate Buffered Saline are both in the 20x concentration to use with immunolabeling techniques. It’s designed to be used as a wash buffer and can be added to promote a more efficient washing. This can result in decreased background staining. Such a product can also be used to encourage reagent spreading using automated staining methodologies.
