Description
Description: Streptavidin is a biotin binding protein present in the fermentation broth of the bacterium Streptomyces avidinii. Each molecule of streptavidin can bind four molecules of biotin with a high affinity constant (Kd~10 -15). Unlike native avidin, streptavidin is not glycosylated and has a near neutral isoelectric point (pI ~ 5-6) vs a pI of 10 for native avidin.

Storage Note
The lyophilized streptavidin is stable when stored at 2-8°C. After reconstitution the streptavidin may be stored as an undiluted liquid at 2-8°C for six weeks. For extended storage as a liquid an equal volume of ACS grade or better glycerol should be added to the vial (bringing the final concentration of streptavidin to 50%) and stored at -20°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. The reconstituted material may also be aliquoted and froze at -70°C without the addition of glycerol.
