Overview

Streptavidin is used as a tetrameric protein used to visualize biotin conjugated molecules in ELISA. Due to the strong affinity of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits. Streptavidin is widely used in molecular biology through its unique high affinity for the biotin.

Recombinant Streptavidin Protein (LumiDye™ Yellow-Green 620) (rp220562) – IF/ICC
IF analysis of GAPDH (red) in MCF-7 cells. The cells were fixed and permeabilized with 100% methanol for 5 minutes, and blocked with 5% BSA for 1 hour at room temperature. Cells were stained with GAPDH Mouse mAb (Biotin) (Ab219252) at a dilution of 1/1000 in blocking buffer for 2 hour at RT and then incubated with Recombinant Streptavidin Protein (LumiDye™ Yellow-Green 620) (rp220562) at a dilution of 1/500 for 1 hour at room temperature in the dark. Cells were counterstained with DAPI (blue). Images were taken on the confocal laser scanning microscope.

Recombinant Streptavidin Protein (LumiDye™ Yellow-Green 620) (rp220562) - Flow Cytometry
Flow cytometry analysis of CD45 expression by Jurkat cells (red) compared to an isotype control (blue). Cells were stained with Recombinant CD45 Antibody (Biotin) (Ab213118) at 0.05μg/test for 1 hour at 4°C. Then incubated with Recombinant Streptavidin Protein (LumiDye™ Yellow-Green 620) (rp220562) at 1μg/test for 30 minutes at 4°C in the dark. Blue - Mouse IgG (Biotin) (Ab180306). Black - Unlabelled control, cells without incubation with primary antibody.
