PC-EIA – Protein C Paired Antibody Set – 5 plate set

SKU: PC-EIA Categories: Antibodies, Paired Antibody Sets, Protein C Products, Protein C Antibody, Protein C EIA Tags: Protein C, Products, Antibodies, Protein C Paired Antibody Set

Description

Protein C Paired Antibody Set

Affinity’s Protein C Paired Antibody Set consists of matched capture and detecting antibodies that have been titrated and optimized for use in sandwich style ELISA assays. The product as provided contains sufficient capture and detecting antibodies for five full 96-well microplates and contains a detailed protocol sheet containing directions for use, recipes for solutions and sources for additional materials required. This Protein C Paired Antibody Set is intended to facilitate the end user in establishing an “in-house” immunoassay for research purposes only and must not be used for diagnostic applications.  Assay validation is the responsibility of the end user.


Product Code: PC-EIA

Supplied Materials:

  1. Capture Antibody (PC-EIA-C): One yellow-capped vial containing 0.5 ml of polyclonal affinity purified anti-Protien C antibody for coating plates.
  2. Detecting Antibody (PC-EIA-D):  One red-capped tube containing 0.5 ml of peroxidase conjugated affinity-purified polyclonal anti-Protein C antibody for detection of captured Protein C.

Description of Protein C

Protein C is a vitamin K-dependent glycoprotein produced in the liver. The concentration of PC in plasma is ~4 μg/ml (~60 nM). A deficiency of Protein C (quantitative or qualitative) is a risk factor for vascular thrombosis. Protein C is expressed as a two-chain molecule with a molecular weight of 62 kDa. The light chain (21 kDa) of PC consists of two EGF-like domains and an amino-terminal domain containing one hydroxyaspartic acid and 11 γ-carboxyglutamic acid (gla) residues. These residues allow PC to bind to membranes that contain acidic phospholipids in a calcium dependent manner. The heavy chain of PC (41 kDa) consists of the catalytic domain and an activation peptide. Activation of Protein C results from cleavage at residue Arg12 in the heavy chain by a complex of thrombin and a cell surface cofactor thrombomodulin. The activation of PC is associated with the release of a small activation peptide (2-3 kDa, called Protein C peptide, or PCP) from the N-terminal of the heavy chain. Activated Protein C (APC) is a serine protease with anticoagulant activity. APC, in complex with a phospholipid membrane, calcium and the Protein S cofactor, exhibits anticoagulant activity through the proteolytic inactivation of coagulation cofactors Va and VIIIa. The primary inhibitor of APC activity in plasma is Protein C Inhibitor (PCI, also called Plasminogen Activator Inhibitor-3, PAI-3) and to a lesser extent by α1antitrypsin and α2macroglobulin. The inhibitory activity of PCI is stimulated approximately 10 fold by heparin1-3.
