n.
Any of several orange-red phycobiliproteins that are found especially in red algae.

phycoerythrin

A phycobilin pigment present in cyanobacteria which can be coupled to antibodies for detecting proteins and antigens due to the extremely bright (red) signal immunofluorescence assays.

phycoerythrin

a red pigment with a photosynthetic function found in red algae and some cyanobacteria, with absorption peaks at 490,546 and 576 nm (see ABSORPTION SPECTRUM).

The raft is red because the cyanobacteria contain the red light-harvesting pigment, phycoerythrin.
Two hours after the challenge, 60 [micro]L diluted suspension of phycoerythrin labeled (red) beads (2 [micro]m in diameter; Polysciences Inc.
phycoerythrin [PE], allophycocyanin [APC]) is excited by a suitable light source and transfers its absorbed energy to an acceptor fluorophore, which then emits this energy as fluorescence at the acceptor-dye wavelength.
Unlike wild type cells, which produce the red pigment phycoerythrin when exposed to green light, these mutants are turquoise in color, revealing a change in the production of phycoerythrin.
Fluorescein isothiocyanate (FITC)-conjugated mouse anti-human CD4 and CD14, phycoerythrin (PE)-conjugated CDS and mouse IgG1 isotype were added into the tubes, then the tubes were incubated at 4 [degrees] C for 30 min in the dark.
