AF647-NHS ester（Cat No.:I014883） is a derivative of Alexa Fluor 647 (AF647), which is a highly fluorescent dye emitting in the far-red region of the spectrum. AF647-NHS ester is designed as a reactive form of AF647 that can be coupled to various biomolecules through amine groups, enabling their specific labeling. As an analogue of AF647, AF647-NHS ester inherits its bright and stable fluorescence properties. This makes it a valuable tool in fluorescence microscopy, flow cytometry, and other applications where far-red fluorescence detection is required.
