Streptavidin conjugates are widely used together with a conjugate of biotin for specific detection of a variety of proteins, protein motifs, nucleic acids and other molecules since streptavidin has a very high binding affinity for biotin. This Streptavidin-R-PE conjugate comprises streptavidin (as the biotin-binding protein) with RPE covalently attached (as the fluorescent label). It is commonly used as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. It is a very valuable tool for biotin-streptavidin-based biological assays and tests using flow cytometry, microplate reader and microarray platforms. This Streptavidin-R-PE product has been tested by immunofluorescent staining with flow cytometric analysis and Multiplex bead-based assay.

Recombinant Streptavidin Protein (PE) (rp230630) - Multiplex bead-based assay Multiplex bead-based assay and High Performance assays use color-coded polystyrene or superparamagnetic beads coated with target-specific antibodies. When these pre-coated beads are incubated with the sample mixture, the target analytes are captured by the beads. These captured analytes are then detected by a cocktail of biotinylated detection antibodies. Following the addition of a streptavidin-PE reporter, chemiluminescence is generated and detected. ·Capture Antibody (Mouse IgG1): 3 μg/scale ·Detection Antibody (Biotin goat Anti-Mouse IgG1): 2500 ng/mL ·SA-PE dilution ratio: 1/100, 1/1000, 1/10000 and 1/100000 Recombinant Streptavidin Protein (PE) (rp230630) is an indispensable fluorescent reporter reagent in the Luminex multiplex detection platform. Relying on its high-affinity binding to biotin and excellent photoluminescent properties, it enables high-sensitivity multiplex analysis. Aladdin has independently developed a series of streptavidin-PE products (rp230625, rp230626, rp230627, rp230628, rp230629 and rp230630) with distinct formulations, all of which demonstrate excellent performance in the Multiplex bead-based assay detection platform.
