Thermo Scientific R-Phycoerythrin is a red-fluorescent, multi-subunit protein that can be crosslinked or conjugated to other molecules to make fluorescent probes. Streptavidin R-PE is very valuable in biotin-streptavidin detection protocols developed for flow cytometry, microplate assays, and microarrays. 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.

R-phycoerythrin is commonly used in immunoas...
