Thermo Scientific™ Tween 20 Washing Buffer, 2% in PBS (20X) is a concentrated phosphate-buffered saline detergent solution formulated for highly effective washing and blocking in immunoassays and immunolabeling workflows. This PBS-T buffer contains an elevated concentration of 2% Tween 20, a gentle nonionic surfactant that enhances washing performance, reduces nonspecific background staining, and improves reagent spreading in automated staining systems.
Supplied as a convenient 20X stock concentrate, this solution is ideal for laboratories requiring a space-saving, ready-to-dilute buffer for routine preparation of working-strength PBS-T wash buffers.
Key Features and Benefits
