Gallery: Streptavidin-HRP #3999
- Western blot analysis of extracts from HeLa cells, untreated or treated with Paclitaxel #9807, using Phospho-Histone H3 (Ser10) (D2C8) Rabbit mAb (Biotinylated) #3642 and Streptavidin-HRP #3999 for detection.
This Cell Signaling Technology product is useful for the detection of biotinylated proteins (1,2). Conjugation of horseradish peroxidase (HRP) to streptavidin is obtained by cross linking the amino groups on streptavidin with the carbohydrate groups on HRP.
Streptavidin is a 53 kDa homotetramer isolated from Streptomyces avidinii for use in isolation and detection bioassays (3). Each streptavidin subunit forms high affinity non-covalent bonds with the vitamin biotin. Because of its strong non-covalent interaction with biotin, streptavidin can be used to detect and isolate biotinylated proteins (1,2).
Chemiluminescent detection systems have emerged as the best all-around detection method for use with western blots and ELISA. These detection assays eliminate the hazards associated with radioactive materials and toxic chromogenic substrates. The speed and sensitivity of these methods are unequalled by traditional alternatives. Streptavidin-HRP is used with biotinylated proteins and specific chemiluminescent substrates to generate light signal. Streptavidin-HRP conjugates have a very high turnover rate, coupling high sensitivity with short reaction times.
