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 chains present 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 as ELISA, IHC, TRFIA, quantifying

 PCR, isolation of single-stranded nucleotide, purification of biomolecule, and monoclonal antibody production as well.

R-mSA is a 118 amino acid protein which is improved in stability and specificity by the removal

 of activity-unrelated sequence compared to native streptavidin.
