ChemiPURE Tween-20 (Polysorbate 20) is a non-ionic surfactant widely used in molecular biology, biochemistry, and immunoassay applications. It is commonly employed as a mild detergent in wash buffers to reduce non-specific binding and background signal in techniques such as ELISA, Western blotting, and immunohistochemistry. ChemiPURE Tween-20 helps stabilize proteins and enzymes without denaturing them, making it suitable for maintaining biological activity while improving assay reproducibility and signal clarity.
