CY3-PEG-MAL MW:550 Fluorescent probe Protein engineering

CY3-PEG-MAL is a fluorescent dye molecule. It consists of a CY3 fluorescent dye with a PEG (polyethylene glycol) linking group and a MAL (maleimide) reactive group.CY3-PEG-MAL is fluorescently active and reactive, and therefore has a wide range of applications in biomedical fields.

One of the applications of CY3-PEG-MAL is as a fluorescent probe. It can interact with specific biomolecules or cells and detect and quantitatively analyze the presence and activity of the target molecule or cell through fluorescent signals. For example, researchers can label CY3-PEG-MAL on a specific antibody and then use fluorescence microscopy to observe the binding of the antibody to the corresponding antigen on the cell surface. This method can be used to study the structure and function of cells as well as the distribution and interaction of specific molecules.

Another application is the use of CY3-PEG-MAL in protein engineering. Researchers can attach CY3-PEG-MAL to proteins and covalently bind them to specific sites through chemical reactions. In this way

Labeling and localization of proteins can be achieved to study the structure, function, and interactions of proteins. For example, researchers can attach CY3-PEG-MAL to the active site of an enzyme and monitor enzyme activity and receptor binding through fluorescent signaling.

In conclusion, CY3-PEG-MAL has a wide range of applications as a fluorescent dye molecule. It can be used in fluorescent probes, protein engineering, and other biomedical studies, providing researchers with an effective tool to explore the structure, function, and interaction of biomolecules.
