I. [Product Description]
This product is benzylguanine-modified polyethylene glycol succinimide active ester (BenzylGuanine-PEG-NH2), which combines a highly reactive amino group and a bioorthogonal functional group. It can be used as an organic intermediate in the fields of protein site-specific labeling and biopolymer coupling. Its tunable PEG chain length (2000-5000 Da) endows the product with excellent water solubility and biocompatibility. At the same time, the benzylguanine module can specifically bind to the SNAP-tag protein system, making it an important functionalized reagent for constructing catalytic reaction systems.
