  • Synonym
  • Source
    Human Serpin G1 Protein, His Tag(SER-H52H5) is expressed from human 293 cells (HEK293). It contains AA Asn 23 - Ala 500 (Accession # P05155-1).
    Predicted N-terminus: Asn 23
  • Molecular Characterization
    Serpin G1 Structure

    This protein carries a polyhistidine tag at the C-terminus

    The protein has a calculated MW of 54.7 kDa. The protein migrates as 75-105 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.1 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Serpin G1 SDS-PAGE

Human Serpin G1 Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

Serpin G1 MALS images

The purity of Human Serpin G1 Protein, His Tag (Cat. No. SER-H52H5) is more than 85% and the molecular weight of this protein is around 65-85 kDa verified by SEC-MALS.

 Serpin G1 ENZYME

.Measured by its ability to inhibit Recombinant Human Complement Component C1s cleavage of a colorimetric peptide substrate, N-carbobenzyloxy-Lys-ThioBenzyl ester (Z-K-SBzl). The IC50 is <4 nM (QC tested).

  • Background
    Serpin G1/C1-inhibitor (C1-INH) is an important regulator of the complement, coagulation, fibrinolytic and contact systems. The quantity of protease/C1-INH complexes in the blood is proportional to the level of the in vivo activation of these four cascade-like plasma enzyme systems. It inhibits activated C1r and C1s of the first complement component and thus regulates complement activation. It is synthesized in the liver, and its deficiency is associated with hereditary angioneurotic oedema (HANE).
