Cy3P

Cy3P refers to a series of cyanine dyes, specifically derivatives of the cyanine 3 (Cy3) fluorophore. These dyes are characterized by their bright fluorescence, good photostability, and excitation and emission spectra that fall within the visible range, typically in the green to orange-yellow region. The "P" designation often indicates a specific modification or functionalization of the basic Cy3 structure, which can alter its properties such as solubility, reactivity, or spectral characteristics.

These Cy3P dyes are widely used in biological and chemical research as fluorescent labels. Their applications include labeling biomolecules like proteins, nucleic acids, and antibodies for detection and imaging in techniques such as fluorescence microscopy, flow cytometry, and Western blotting. The specific modifications in Cy3P variants can be tailored to facilitate conjugation to different target molecules or to enhance performance in particular assay formats. Researchers select specific Cy3P derivatives based on the desired wavelength, brightness, conjugation chemistry, and experimental conditions. The development of Cy3P and similar cyanine dyes has been instrumental in advancing fluorescent-based detection methods in various scientific disciplines.
