I. [Product Introduction]
Casein-PEG-NHS is a highly efficient organic intermediate based on the modification of casein and polyethylene glycol, which can serve as a key linker in bioconjugation reactions. The N-hydroxysuccinimide ester group (NHS) in its structure endows it with excellent activation performance, making it suitable for protein carrier construction and functional material development. The customizable molecular weight feature significantly enhances the application flexibility.
