Format
Lyophilized
Reconstitution
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Buffer
Lyophilized from a 0.2 μm filtered solution of 50 mM TrisHCl, 150 mM NaCl, 10 mM NaCl, pH 8.0.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
Stock
4 °C/-20 °C/-80 °C
Stockage commentaire
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.
Date de péremption

Sujet
Serpin Peptidase Inhibitor, Clade A (alpha-1 Antiproteinase, Antitrypsin), Member 4 (Serpin A4) is a member of the Serpin family. Serpin A4 exists as a monomer and some homodimers. Serpin A4 is expressed by the liver and secreted in plasma. Serpin A4 is a regulator of vascular homeostasis capable of controlling a wide spectrum of biological actions in the cardiovascular and renal systems. It can inhibit intracellular reactive oxygen species formation in cultured cardiac and renal cells. In addition, Serpin A4 has anti-inflammatory effect. Heparin blocks kallistatin's complex formation with tissue kallikrein and abolishes its inhibitory effect on tissue kallikrein's activity. Alternative Names: Kallistatin, Kallikrein Inhibitor, Peptidase Inhibitor 4, PI-4, Serpin A4, SERPINA4, KST, PI4
