Streptavidin Protein, DyLight™ 405

Streptavidin for Western Blot, ICC/IF, IHC, IP, ELISA

Streptavidin is a tetrameric protein purified from Streptomyces avidinii 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.
