一般描述

背景

链霉亲和素是一种来自streptomyces avidinii菌的非糖基化蛋白。链亲和素同源四聚体对生物素具有特别高的非共价结合亲和力。当与酶（如辣根过氧化物酶或碱性磷酸酶）形成偶联物并与比色或发光底物发育系统结合时，链霉亲和素与生物素化抗体在许多应用中得到广泛应用，包括Western blot、ELISA、ELISPOT、免疫细胞化学和免疫组化。

推荐工作浓度

WB : 1:10000-1:100000

ELISA: 1:1000-1:10000

避免使用含有生物素的稀释液，试剂不得含有叠氮化钠，叠氮化钠会抑制辣根过氧化物酶的活性。实际试验操作过程中可根据具体实验情况适当调整Streptavidin(HRP)的稀释比例。

Background

Streptavidin is a non-glycosylated protein from the bacterium Streptomyces avidinii. Streptavidin homotetramers have a particularly high, non-covalent binding affinity for biotin. When conjugated with an enzyme (eg, Horseradish Peroxidase or Alkaline Phosphatase) and coupled with a colorimetric or luminescent substrate development system, streptavidin has found widespread use along with biotinylated antibodies in a number of applications including Western blot, ELISA, ELISPOT, immunocytochemistry and immunohistochemistry.

Recommended Usage：

WB: 1:10000 -1:100000

ELISA: 1:1000-1:10000

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.
