Streptavidin Protein-HRP, Horseradish peroxidase conjugated Streptavidin
分子别名（Synonym）
Streptavidin,SA
表达区间及表达系统（Source）
Streptavidin is expressed from E. coli cells and conjugated with horseradish peroxidase under optimal conditions.
蛋白结构（Molecular Characterization）
This protein carries no "tag".
The protein has a calculated MW of 13.8 kDa.
应用说明（Application）
Recommended for use in ELISA (0.1 µg/mL), immunohistochemistry, and western blot applications.
Avoid using biotin-containing solutions as diluents and solutions containing sodium azide. Sodium azide is an inhibitor of horseradish peroxidase. It is recommended that the reagent be titrated for optimal performance for each application.
NOTE: Do not use skim milk as a blocking agent in the assay with streptavidin, since skim milk contains free biotin which will cause high backgrounds.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
链霉亲和素（Streptavidin）是一种从阿维丁链霉菌中纯化的66 kDa四聚体蛋白，对生物素具有高结合亲和力，每个亚基可结合一个生物素分子。辣根过氧化物酶（HRP）是一种44 kDa糖蛋白类金属酶，经底物孵育后能产生可检测定量的显色、荧光或发光衍生物。HRP标记的链霉亲和素偶联物广泛应用于生物素标记蛋白的检测与定量分析。
