APN-C2-NHS ester

APN-C2-NHS ester is a small molecule linker that contains several functional groups, including an amino group, a carboxyl group, and a succinimidyl ester group. The amino group can react with other molecules that contain carboxyl or other reactive groups, forming covalent bonds between the two molecules. The succinimidyl ester group is a commonly used reactive group in bioconjugation, which can react with primary amines in proteins or peptides to form stable amide bonds.

In the context of bioconjugation, APN-C2-NHS ester can be used to label proteins, peptides, or other biomolecules with a variety of functional groups, such as fluorescent dyes, biotin, or drugs. The resulting conjugates can be used for a wide range of applications, including biomolecular imaging, drug delivery, and diagnostics.
