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 three major phycobiliproteins commonly found in cyanobacterial phycobilisomes are; Phycocyanin (PC), Allophycocyanin (APC) and Phycoerythrin (PE).
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.
Although several nuclear genes have been identified and partially sequenced, the only identified gene presumed to code for a plastid component is cpeA, the alpha subunit of phycoerythrin.
sup][16] Briefly, peripheral blood cells were stained simultaneously using an antihuman fluorescein isothiocyanate-conjugated lineage cocktail, phycoerythrin (PE)-conjugated CRTH2, and PE-CY7-conjugated CD127, or appropriate isotype controls (all from BD Pharmingen, San Diego, CA, USA).
As part of this study, we compared antibodies conjugated with FITC or phycoerythrin (PE).
