Tween 20 usage:
Tween 20 is a detergent that can interfere with ELISA and potentially other applications (often used in antibody dilution buffers, such as TBST) when using anti-PEG products. Our anti-mPEG antibody [PEG-B-47] reacts to the methoxy group of Polyethylene glycol (PEG). There is no methoxy group in Tween 20, which should not interfere with the function of this antibody.
