Recombinant human Fetuin B protein expressed in HEK293 mammalian cells and supplied as a lyophilized preparation with a C-terminal His tag. The protein is >95% pure by reducing SDS-PAGE, shows biological activity in Cathepsin V inhibition assays (IC50 ≈ 21.16 nM), and includes datasheet and certificate of analysis. Recommended reconstitution and storage instructions are provided for assay use.
- High purity (>95%) as determined by reducing SDS-PAGE.
- Mammalian (HEK293) expression preserves native glycosylation.
- C-terminal His tag facilitates downstream purification or detection.
- Demonstrated biological activity with IC50 ≈ 21.16 nM against Cathepsin V.
- Lyophilized formulation for extended shelf life and convenient storage.
- Formulated in physiological buffer; store lyophilized at -20 °C and freeze aliquots at -20 °C or -80 °C after reconstitution for long-term storage.
