PerCP (Peridinin-Chlorophyll-Protein) antibody conjugates are essential tools for multicolor flow cytometry, offering excitation by the 488 nm laser with emission in the far-red region (~675 nm). AAT Bioquest provides a comprehensive selection of PerCP-conjugated primary antibodies targeting key immune cell markers, enabling researchers to build robust multicolor panels for immunophenotyping applications. These conjugates are particularly valuable when combined with FITC and PE conjugates on the same laser line, allowing efficient use of instrument configurations.

PerCP-conjugated CD antibodies utilize a natural photosynthetic pigment-protein complex from dinoflagellates, providing bright far-red fluorescence (~675 nm) when excited by the common 488 nm laser. With minimal spectral overlap with FITC and PE channels, PerCP is an excellent third-color choice for basic multicolor immunophenotyping panels. For additional spectral flexibility, PerCP tandem conjugates (such as PerCP-Cy5.5) use fluorescence resonance energy transfer (FRET) to shift emission further into the red region (~695 nm). This extended wavelength provides better separation from PE-based tandems and enables more complex panel designs on single-laser instruments.
