General description

Streptavidin-R-Phycoerythrin is a fluorescent labeling agent comprised of a biotin-binding protein (streptavidin) covalently attached to a fluorescent label ((R-phycoerythrin). Streptavidin-R-phycoerythrin complexes provide the measurement method for the target phosphoprotein. And, Streptavidin R-phycoerythrin extends the light tolerance of certain phycobiliproteins.

Application

Streptavidin-R-Phycoerythrin (R-PE) is used to label biotin-conjugated (biotinylated) molecules and biotin derivatized surfaces in a wide variety of immunofluorescence applications such as immunochemistry and histochemistry. Streptavidin-R-Phycoerythrin may be used in the development of bioassay devices such as Lab-on-a-chip (LoC) systems and microarrays.
