Streptavidin, R-Phycoerythrin Conjugate(SAPE) - premium grade - 1 mg/mL

Product introduction:The R-phycoerythrin (R-PE) conjugate of streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (R-phycoerythrin). Streptavidin has a very high binding affinity for biotin, and a conjugate of streptavidin is commonly used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids, and other molecules (for example, a biotinylated primary antibody bound to a protein target can be detected with a fluorescently labeled streptavidin). Streptavidin R-PE is very valuable in biotin-streptavidin detection protocols developed for flow cytometry, microplate assays, and microarrays. This R-PE streptavidin conjugate is a high-purity product (purity confirmed by HPLC) and is supplied as 1 mL of a 1 mg/mL solution.Important Features of Streptavidin RPE:• :Ex/Em maxima of ∼ (496, 546, 565/578) nm:• :5 to 10 times brighter than organic dyes:• :Very high solubility in aqueous solutions:• :Free of all unconjugated streptavidin: and mostly free of unconjugated R-PE:• :Ideal for flow cytometry, microplate assays, and microarrays:Properties of R-phycoerythrin:R-PE has a quantum efficiency of 78%, making it an incredibly bright reagent, useful where high sensitivity is needed. Because of poor photostability, however, it is not recommended for fluorescence microscopy.Find Biotinylated Conjugates:We offer an extensive line of biotinylated conjugates for use in biotin-streptavidin detection strategies.• Use theLearn more about Avidin-Biotin Detection:Learn more about the practical applications for Streptavidin R-PE:• :Conjugate:R-Phycoerythrin
