Streptavidin, Recombinant, Lyophilized, 1 mg

Streptavidin is a homo-tetrameric protein found in the culture broth of 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 a neutral isoelectric point, which reduces nonspecific binding compared to avidin. Streptavidin is extensively used for various biological applications, including ELISA, IHC, TRFIA, quantification of PCR product, isolation of single-stranded nucleotide, purification of biomolecule, and monoclonal antibody production as well. Compared to native streptavidin, our recombinant streptavidin has improved stability and solubility through the removal of activity-unrelated amino acid sequences.
