Description:

Streptavidin is a homotetrameric protein secreted from Streptomyces avidinii. Similar to avidin, one mole of streptavidin can bind 4 moles of biotin with a high affinity . Streptavidin lacks carbohydrate side chainspresent on avidin and has an isoelectric point close to neutrality. Therefore it has a reducing nonspecific binding level as compared to avidin. Streptavidin has been extensively applied in various biological fields, such asELISA, IHC, TRFIA, quantifying PCR,isolation of singlestranded nucleotide, purification of biomolecule, and monoclonal antibody production as well.RmSA is a 118 amino acid protein which is improved in stability and specificity by the removal of activity-unrelated sequence compared to native streptavidin.
