Serine Peptidase Inhibitor Clade A Member 3 (SERPINA3), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as enzymetic analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the human SERPINA3 (NP_001076.2) (Met 1-Ala 423) fused to a C-terminal polyhistidine tag.

Activity: Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (Anaspec, Catalog# 27114). The IC50 value is<20 nM.

Formulation: Lyophilized in 25 mM HEPES, 0.15 M NaCl, pH 7.8, 5% Mannitol, 5% Trehalose, 0.02% Tween80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.

This protein is manufactured by Sino Biological Inc.
