  • 相关性Streptavidin 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.

ab123480 is the full length streptavidin protein and actively binds biotin.

The laboratory has not had experience using streptavidin protein, followed by primary anti-streptavidin and secondary labeling via western blot. They suggested us...
