Streptavidin/链（霉）亲和素
产品编号：PRO-283
产品规格：2mg/10mg/100mg
Introduction Streptavidin is a tetrameric protein secreted by Streptomyces avidinii which binds firmly to biotin. Streptavidin is wilyde used in molecular biology through its unique high affinity for the vitamin biotin. The dissociation constant （Kd） of the biotin-streptavidin complex is about ~10-15 mol/L. The strong affinity recognition of biotin ａnd biotinylated molecules has made streptavidin one of the most important components in diagnostics ａnd laboratory kits. The streptavidin/biotin system has one of the biggest free energies of association of yet observed for noncovalent binding of a protein ａnd small ligand in aqueous solution （K_assoc = 10**14）. The complexes are also extremely stable over a wide range of temperature ａnd pH. Description The Streptavidin preparation contains an N- ａnd C-terminal shortened variant （core streptavidin） with improved properties concerning homogeneity, solubility, resistance towards proteolytic degradation ａnd accessibility of the biotin binding pocket as compared to native streptavidin. Streptavidin has a molecular weight of 53 kDa. Source Bacterium Streptomyces avidinii. Physical Appearance Sterile Filtered lyophilized powder. Formulation Lyophilized in 10mM potassium phosphate buffer pH 6.5. Solubility Gives a clear solution at 5mg/ml in 0.1M NaCl. Stability Streptavidin although stable at 4°C for 3 weeks, should be stored desiccated below -18°C.
For longer storage in dissolved form add 1mM EDTA and/or 0.02 % NaN3 or pass the solution through a sterile filter.
Please prevent freeze-thaw cycles. Application Streptavidin may be used to visualize biotin conjugated molecules in ELISA, blotting ａnd histological technique. Specific Activity Greater than 15.3 U/mg, 1 unit binds 1μg biotin. Proteolytic Activity Less than 10-3 U/mg protein （Azocoll, 25°C, 24 h, pH 8.0）. Purity Greater than 95.0% as determined by SDS-PAGE. Usage Prospec＇s products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.

Streptavidin/链（霉）亲和素
产品编号：PRO-283
产品规格：2mg/10mg/100mg
Introduction Streptavidin is a tetrameric protein secreted by Streptomyces avidinii which binds firmly to biotin. Streptavidin is wilyde used in molecular biology through its unique high affinity for the vitamin biotin. The dissociation constant （Kd） of the biotin-streptavidin complex is about ~10-15 mol/L. The strong affinity recognition of biotin ａnd biotinylated molecules has made streptavidin one of the most important components in diagnostics ａnd laboratory kits. The streptavidin/biotin system has one of the biggest free energies of association of yet observed for noncovalent binding of a protein ａnd small ligand in aqueous solution （K_assoc = 10**14）. The complexes are also extremely stable over a wide range of temperature ａnd pH. Description The Streptavidin preparation contains an N- ａnd C-terminal shortened variant （core streptavidin） with improved properties concerning homogeneity, solubility, resistance towards proteolytic degradation ａnd accessibility of the biotin binding pocket as compared to native streptavidin. Streptavidin has a molecular weight of 53 kDa. Source Bacterium Streptomyces avidinii. Physical Appearance Sterile Filtered lyophilized powder. Formulation Lyophilized in 10mM potassium phosphate buffer pH 6.5. Solubility Gives a clear solution at 5mg/ml in 0.1M NaCl. Stability Streptavidin although stable at 4°C for 3 weeks, should be stored desiccated below -18°C.
For longer storage in dissolved form add 1mM EDTA and/or 0.02 % NaN3 or pass the solution through a sterile filter.
