一、基本信息

【性质简介】：The tetrasulfonic acid structure of AF555 dye seems to endow it with a unique magic, giving it extremely hydrophilic properties. This characteristic ensures that the dye does not alter the polarity of the protein surface when labeled, greatly reducing the risk of protein aggregation ａnd precipitation due to hydrophobicity. In biomarker reactions, NHS activated esters are like a clever key that always finds the right position to function. It activates AF555 by binding to the carboxyl group in the molecule, enabling it to react with the amine group (mainly primary amine) on the target biomolecule, generating stable amide bonds. This labeling process not only preserves the original structure ａnd function of biological macromolecules, but also endows them with new fluorescence characteristics, allowing scientists to easily track ａnd locate target molecules in complex biological systems.
