特徴

• Serpin A5, also known as PCI (Protein C Inhibitor) or PAI3 (plasminogen activator inhibitor 3), is a member of the serpin serine proteinase inhibitor family. This protein inhibits plasminogen activators as well as activated protein C. Serpin A5 is secreted in plasma, but is also expressed in liver. Serpin A5 is involved in cell inflammation, proliferation, apoptosis, tumor cell migration, invasion, and metastasis. Recombinant human Serpin A5, fused to His-Tag at N-terminal, expressed in E. coli and purified by using conventional chromatography techniques.
