Streptavidin Resin is an affinity chromatography medium designed for easy, one-step purification of biotinylated peptides, antibodies, lectins, etc from samples.
特异性
Resin Volume 5 ml settled resin (10 ml 50% slurry) Ligand Streptavidin, affinity purified with IminoBiotin Resin (L00272) Number of biotin binding sites per ligand 4 M.W. of ligand Approximately 54 kDa PI of ligand 6.52 Degree of substitution Approximately 2 mg streptavidin/ml settled resin Total binding capacity > 120 nmol of D-Biotin/ml settled resin Matrix spherical agarose, 4% cross-linked Average particle size 90 μm (45 - 165 μm) Storage solution 1X PBS containing 20% ethanol Storage conditions 2 - 8°C Shelf life 12 months when stored unopened
产品特性
The purified recombinant streptavidin is covalently coupling to 4% highly cross-linked agarose. The coupling is optimized to give high binding capacity for biotinylated molecules. The total binding capacity of Streptavidin Resin is more than 120 nmol of D-Biotin/ml settled resin.

背景
Streptavidin is a biotin-binding protein found in the culture broth of the bacterium Streptomyces avidinii. Streptavidin binds 4 moles of biotin per mole of protein with an extremely high affinity. Streptavidin lacks carbohydrate side chains present on avidin and has an isoelectric point of 6.5 (vs 10 for avidin) close to where most useful biological interactions occur. As a result, streptavidin frequently exhibits much lower non-specific binding than avidin does.
