Peridinin-Chlorophyll-Protein (PerCP) is a peridinin-chlorophyll-protein complex with a molecular weight of 35.5 kDa, isolated from Dinophyceae sp. It features a broad excitation spectrum with a main peak at 482 nm, a large Stokes shift, and its maximum emission peak is at 677 nm. PerCP and its conjugates are large complexes suitable for cell surface labeling techniques (e.g., flow cytometry).
Product Properties
Molecular Weight: Approximately 35,500 Daltons
Quantification: For accurate quantification of PerCP, we recommend using its extinction coefficient (i.e., [PerCP] = 0.086 × A482, where [PerCP] is the concentration in mg/ml, and A482 is the absorbance at 482 nm with a control range of 0.3–0.8).
Purity: A482/A280 > 4.0
Excitation Wavelength: 488 nm
Form: Ammonium sulfate precipitate
