Mechanism of reaction:
AF555 NHS activated ester is a chemical substance that is widely used in biology and medicine. It has very important application value, especially in the design of protein labels and biological probes. AF555 NHS activated ester is a fluorescent dye with excellent optical properties and stability that can be used under a wide range of physiological conditions.
For protein labeling, AF555 NHS-activated ester can attach fluorescent dyes to proteins by reacting with amino groups to produce stable covalent conjugates. This process, called activated ester method, is a very effective method of protein labeling. The labeled proteins can be used in a variety of biological experiments, such as immunofluorescence detection, protein-protein interaction studies, and cell imaging.
In addition, AF555 NHS-activated ester can also be used in the design of bioprobes. Biological probes are tools used to detect target molecules in biological samples, and AF555 NHS-activated ester can be used as a fluorescent marker to emit a fluorescent signal when bound to the target molecule, enabling visual detection of the target molecule. This technology has a wide range of applications in the fields of molecular biology, biomedical engineering, and drug discovery.
