PerCP is a red-emitting fluorescent protein originating from dinoflagellates, which are a class of brown microalgae recognized for their distinctive light-harvesting complexes. PerCP is widely utilized in flow cytometry and fluorescence-based immunolabeling due to its distinct spectral properties. It is efficiently excited at 482 nm by the 488 nm blue laser and detected through a 670/30 nm bandpass filter. With a large Stokes shift, PerCP offers superior spectral separation, making it an ideal fluorophore for multi-color flow cytometry panels.

(SMCC R-PE)
SMCC R-PE is a chemically modified fluorescent protein optimized for thiol-based conjugation. Engineered with maleimide (-NH2) functional groups, it efficiently reacts with sulfhydryl (-SH) groups of target proteins, enabling high-yield, stable covalent labeling without requiring additional activation.
With a primary absorption peak at 565 nm and secondary peaks at 496 nm and 545 nm, SMCC R-PE provides a broad excitation spectrum, making it highly suitable for multi-color immunofluorescence, antibody conjugation, and flow cytometry-based cell sorting. Compared to conventional organic fluorophores, SMCC R-PE conjugates offer higher brightness, superior photostability, and minimal spectral overlap, ensuring enhanced signal-to-noise ratios in live-cell staining, immunofluorescence assays, and biomarker detection.
B-PE is a highly fluorescent phycobiliprotein extracted from Porphyridium Purpureum (red microalgae). Renowned for its intense red-orange fluorescence, high quantum yield, and exceptional brightness, B-PE serves as a valuable fluorophore in flow cytometry, fluorescence microscopy, immunoassays, and multiplex bead-based applications.
Its broad excitation spectrum (545 nm) and strong emission (572 nm), combined with high photostability and minimal spectral overlap, make it an ideal marker for multi-color detection in biotechnology, medical diagnostics, and immunological research.
