Streptavidin, Streptomyces avidinii


Chemical Properties

Lyophilized powder, 13.5 kDa
Gives a clear solution at 5mg/ml in 0.1M NaCl. is soluble in water at 1 mg/mL, or in phosphate buffered saline (PBS).


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.


Reconstitute at 1mg/ml in water or PBS
