Product details:
The smallest PEG molecule which our antibody can detect is PEG750. Based on customer feedback, the largest PEG molecule detected is PEG 40K. Additionally, ab271853 detects both linear and branched PEG based on our in-house ELISA testing.
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-47b] 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.
