STREPTAVIDIN

Description of Target: Streptavidin is a bacterial protein (from Streptomyces avidinii) that has an exceptionally high binding affinity for biotin (B7). Streptavidin-biotin binding is one of the strongest known non-covalent interactions and is highly resistant to many conditions that would typically cause dissociation (such as organic solvents, denaturants, detergents, and extreme temperatures or pH). Streptavidin's affinity for biotin can be employed in a variety of experimental uses, from purifications to standards, to means of detection or pull down experiments.

Product Format: Lyophilized. 0.15 M Sodium Chloride.

Purification: Streptavidin is chromatographically pure.

Specificity: Shows predominantly a single 53,600 dalton band by SDS-PAGE.
