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™ Red 660) (rp220564) - 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™ Red 660) (rp220564) at 0.05μg/test for 30 minutes at 4°C in the dark. Blue - Mouse IgG (Biotin) (Ab180306). Black - Unlabelled control, cells without incubation with primary antibody.
