SC-PEG-SC是一种与胺基反应的双功能交联PEG试剂，是NHS-PEG-NHS酯试剂的一类。在我们提供的所有这些NHS酯中，SC是一种非常活跃的NHS酯。SC代表琥珀酰亚咪酯。NHS酯通过碳酸盐连接到PEG上，在与胺反应后，它在PEG和含胺分子之间形成稳定的氨基甲酸酯键。

SC-PEG-SC is a bifunctional crosslinking PEG reagent to react with amine groups, and it is one type of the NHS-PEG-NHS ester reagents. Among all these NHS esters we offer, SC is a very reactive NHS ester. SC stands for succinimidyl carbonate. The NHS ester is attached to PEG through a carbonate linkage and upon reacting with amine, it forms a stable carbamate bond between the PEG and the amine-containing molecule.
