mouse monoclonal IgG1; anti-Cy3 Antibody (A-6) is an IgG1 κ mouse monoclonal anti-Cy3 antibody (also designated anti-Cy3 antibody) that detects the anti-Cy3 protein. anti-Cy3 Antibody (A-6) is available as both the non-conjugated anti-anti-Cy3 antibody form, as well as multiple conjugated forms of anti-anti-Cy3 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Cyanine is a non-systematic name of a synthetic dye family belonging to the polymethine group. The family of cyanine dyes include Cy2, Cy3, Cy5, Cy7 and their derivatives, which the numbers are based on the partially saturated indole nitrogen heterocyclic nucleus with two aromatic units being connected via a polyalkene bridge of varying carbon number. Cyanines have many uses as fluorescent dyes, particularly in biomedical imaging. Depending on the structure, they cover the spectrum from infrared to ultraviolet. Cyanines are utilized to increase the sensitivity range of photographic emulsions, such as increasing the range of wavelengths which will form an image on film. Cyanines are mostly green or light blue in color, and are chemically unstable. Anti-Cyanine may be immobilized and used to bind the Cyanine dyes in a linker system. A linker system is provided where a small molecule reactive group, e.g., an activity based probe which binds to certain enzymes at the active site, is linked through an aryl diazo linker to an affinity molecule.
