Recombinant Minimum Streptavidin used in isolation of single-stranded nucleotide
Theoretical Activity: 19.7 U/mg protein (r-mSA:Biotin = 1:4 (mol:mol))
Activity: ≥17 U/mg protein (Determined by NUPTEC according to modified Green Method)
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.
