Beschreibung: Phycoerythrin is one of a series of fluorescent pigments known as phycobiliproteins, whichare produced by red and blue green algae. It occurs in more than one form, and has foundapplication in immunology and diagnostic medicine. B and R Phycoerythrins providesuperior labeling compared to fluorescein and rhodamine, and are used for labelingantibodies, usually monoclonals. These dyes may also be coupled to enzymes and otherproteins, nucleic acids, polypeptide hormones, drugs, etc. Since phycoerythrins absorblight maximally between 450 and 650nm they fill the need for an intense fluorescent dye inthe longer wavelengths of the visible spectrum, thereby avoiding interference fromnaturally fluorescing biological substances. R Phycoerythrin (240 kDa) is a labile moleculethat may dissociate into components upon exposure to reducing or denaturing agents.

Spezifität: Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-GoatSerum and R-Phycoerythrin conjugated IgG. This antibody will cross react with B-Phycoerythrin. Reactivity with other phycobiliproteinsis unknown.

Anwendungen

Applikationshinweise: Suitable for Immunoblotting (western or dot blot), ELISA as well as other Immunochemicalassays. R-Phycoerythrin (240 kDa) is a labile molecule that may dissociate intocomponents upon exposure to reducing or denaturing agents. Reaction with low molecularweight fragments is typically noted by western blot. Recommneded Dilutions: ELISA: 1/200,000. Western Blot: 1/2000-1/20,000. Immunohistochemistry: 1/500-1/3,000. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
