Specifications

Product Data

• Species: Human
• Expression Host: HEK293
• Expression cDNA Clone or AA Sequence:
  Protein Sequence

  Gln21-Pro427
• Tag: C-His
• Predicted MW: 47.1 kDa
• Concentration: lot specific
• Purity: >95% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: Lyophilized from a 0.2 um filtered solution of 50mM TrisHCl, 150mM NaCl, 10mM NaCl, pH 8.0.
• Endotoxin: Endotoxin level is < 0.1 ng/µg of protein (< 1 EU/µg)
• Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. Dissolve the lyophilized protein in ddH2O. It is not recommended to reconstitute a concentration less than 100 µg/ml. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
• Stability: Stable for at least 6 months from date of receipt under proper storage and handling conditions.

Reference Data

• RefSeq: NP_006206

• UniProt ID: P29622, A0A024R6I9
• Cytogenetics: 14q32.13
• Refseq Size: 1700
• Refseq ORF: 1281
• Synonyms: KAL; kallistatin; KLST; KST; PI-4; PI4
• Summary: Inhibits human amidolytic and kininogenase activities of tissue kallikrein. Inhibition is achieved by formation of an equimolar, heat- and SDS-stable complex between the inhibitor and the enzyme, and generation of a small C-terminal fragment of the inhibitor due to cleavage at the reactive site by tissue kallikrein.[UniProtKB/Swiss-Prot Function]
• Protein Families: Druggable Genome, Secreted Protein
