Background

Serpina 4, also called Kallistatin, PI4 or TISSUE KALLIKREIN INHIBITOR, is a protein that in humans is encoded by the SERPINA4 gene. The serpina4 is a member of the serpin superfamily and represents a major inhibitor of human tissue kallikrein in the circulation. The SERPINA4 gene is localized to 14q32.13. The translated amino acid sequence of serpina4 matches the protein sequence and shares 44 to 46% sequence identity with other serpin family members. Kallistatin is a serine proteinase inhibitor (serpin) and a heparin-binding protein. It is localized in vascular smooth muscle cells and endothelial cells of blood vessels, suggesting that it may be involved in the regulation of vascular function. And serpina4 also plays a role in neointima hyperplasia.

Immunogen

A synthetic peptide corresponding to a sequence at the C-terminus of human Kallistatin.

Clonality

Polyclonal

Tissue Specificity

Expressed by the liver and secreted in plasma.

Applications

IHC,WB

Purification

Immunogen affinity purified.

Concentration

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Form

Lyophilized

Reconstitution

Add 0.2ml of distilled water will yield a concentration of 500ug/ml.

Function

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. .

Components

Each vial contains 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3.
