Species: Streptomyces avidinii
Product Description: Streptavidin is a 55 kDa (subunit MW 14 kDa) biotin-binding protein isolated from Streptomyces avidini. Streptavidin is superior to avidin, because it does not contain carbohydrate like avidin and has no net charge at neutral pH. Streptavidin~biotin system is routinely used in Immunohistochemistry (IHC). Extinction Coefficient 1% A280=32.0. Protein content: > 95%.
Form: Liquid
Buffer (with preservative): 0.1M Bicarbonate (pH8.0), 0.05% Sodium azide.
Concentration: 1 mg/ml (Please refer to the vial label for the specific concentration.)
Background: Streptavidin is a 55 kDa (subunit MW 14 kDa) biotin-binding protein isolated from Streptomyces avidini. Streptavidin is superior to avidin, because it does not contain carbohydrate like avidin and has no net charge at neutral pH. Streptavidin~biotin system is routinely used in Immunohistochemistry (IHC). Extinction Coefficient 1% A280=32.0. Purity: > 99% pure by HPLC; Eletrophoretically homogenous, single band. Protein content: > 95%; Activity 14.8 units/ mg, one unit binds 1.0 microgram of d-biotin; Protease activity: 0.000018 units/mg; Isoelectric point: 7.0 +/- determined by Isoelectric focusing.
Region Sequence: Native Protein
ExpressionSystem: Native Protein
Conjugation: Unconjugated
