Streptavidin-R-Phycoerythrin (ver 2), 50 mg (formerly ProZyme). Streptavidin-R-Phycoerythrin is a conjugate that is predominantly a single peak on an HPLC chromatogram. This is consistent with approximately two streptavidin molecules conjugated to a single R-phycoerythrin molecule. Potential applications include single molecule detection systems and quantitative analysis in flow cytometry.
