Catalog No. NC3823867
Encompass_Preferred

Recombinant streptavidin is a high-purity, premium-grade tetrameric protein produced in E. coli that provides strong, specific biotin binding for assay development, biochemical assays, and early preclinical workflows. It is supplied lyophilized for convenient storage, with low endotoxin and host-cell impurities to support sensitive assays and cell-based applications.

  • High purity (>95%) verified by SDS-PAGE and SEC-MALS.
  • Expressed in E. coli and supplied lyophilized (liquid for larger bulk sizes).
  • Calculated monomer mass 13.4 kDa; tetramer ~45-60 kDa.
  • Low endotoxin (<0.01 EU/μg) for sensitive applications.
  • Low host cell protein and DNA levels (<0.5 ng/μg HCP; <0.02 ng/μg HCDNA).
  • Specific activity ≥15.0 U/mg.
  • Stable 24 months when stored lyophilized at -20°C or lower; reconstituted stability 3 months at -70°C.
  • Suitable for assay development and early preclinical cell-culture workflows.
