Peridinin Chlorophyll (PerCP)


SureLight® PerCP 

Pricing and product specifications

Peridinin Chlorophyll (PerCP) is commonly used in immunoassays such as FACS and flow cytometry.


Structural Characteristics

Peridinin is a light-harvesting pigment associated with chlorophyll and found in the peridinin chlorophyll binding protein (PerCP); a light harvesting protein found in dinoflagellates. The PerCP complex has a high ratio of peridinin to chlorophyll; most light-harvesting complexes contain more chlorophyll than carotenoids, but the PerCP contains eight peridinin and two chlorophyll molecules arranged to promote peridinin-chlorophyll energy transfer. The PerCP complex is a trimer with a molecular weight of 35kDa.
