R-PHYCOERYTHRIN EA，46185，赛默飞世尔

Thermo Scientific R-Phycoerythrin is a red-fluorescent, multi-subunit protein that can be crosslinked or conjugated to other molecules to make fluorescent probes.

Features of R-Phycoerythrin:

• R-Phycoerythrin—red-fluorescent, multi-subunit protein in the phycobiliprotein family
• Large Stokes shift —excitation (absorption) at one of three wavelengths produces light emission at a much higher wavelength

This fluorochrome is a member of the phycobiliprotein family of proteins isolated from the marine algae Porphyra tenera or Gastroclonium coulterii. Fluorochrome-labeled reagents have high resolution and are therefore advantageous in immunological assays, such as live cell staining, double-labeling techniques and cell sorting procedures. The strong absorption bands of the R-Phycoerythrin are in the visible region of the spectrum, extending from the green to the far-red wavelengths. The absorbance spectra extends over a broad range of potential excitation wavelengths, allowing for versatility in the excitation source and creating large Stokes shifts, thus minimizing interference from Rayleigh-scattered light.
