  • RelevanceStreptavidin is a tetrameric protein purified from Streptomyces sp. that binds very tightly to the vitamin biotin with a Kd of ~ 10-14 mol/l. The high affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits.

  • Immunofluorescence analysis of Potorous tridactylis kidney (PtK2) cells, staining Streptavidin with ab10020.

    Cells were fixed with 4% paraformaldehyde, before being incubated with wt streptavidin (2 µM) for 5 min at room temperature. Samples were incubated with 1 µL primary antibody for 1 hour at 4°C. A FITC-conjugated goat anti-mouse IgG was used as the secondary antibody.
