Streptavidin-Peroxidase from Streptomyces avidinii

Descrição detalhada : Steptavidin is coupled to horseradish peroxidase (HRP) using citrate buffer, pH 6.0, and a modified published procedure to form a 1:1 conjugate. HRP has a molecular mass of ~44kDa and steptavidin has a molecular mass of ~60kDa., Streptavidin is considered as a high-affinity biotin-binding agent, which shows resistance to extreme pH, detergents temperature, denaturants and enzymes, hence it is used in molecular biology and bionanotechnology., Streptavidin derives its name from its bacterial source Streptomyces avidinii and from the hen egg-white protein, avidin, which has high affinity to biotin. Its homologous core shares 33% sequence similarity with avidin, as well as sharing a common tetrameric structure. It is a crystalline tetrameric protein, with a molecular weight of 4*15000Da. It binds four molecules of biotin. Streptavidin lacks carbohydrate and sulfur-containing amino acids.
