Function
Thrombin inhibitor activated by the glycosaminoglycans, heparin or dermatan sulfate. In the presence of the latter, HC-II becomes the predominant thrombin inhibitor in place of antithrombin III (AT-III). Also inhibits chymotrypsin, but in a glycosaminoglycan-independent manner.Peptides at the N-terminal of HC-II have chemotactic activity for both monocytes and neutrophils.
Alternative names
Heparin cofactor 2, Heparin cofactor II, Protease inhibitor leuserpin-2, Serpin D1, HC-II, HLS2, HCF2, SERPIND1

- - Simoa® and Single Molecule Counting (SMC™) immunoassays
- - Multiplex
- Our antibody pairs are supplied in a a carrier-free format that is conjugation-ready:
- - Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
- - Concentration of ~1 mg/ml as measured by the protein A280 method.
- Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for biotin, HRP, gold, and fluorescent dyes.
- We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation service
- Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.
- Please note:
- The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.
- The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.
- We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Supplementary info
- Activity summary
HC-II also known as heparin cofactor II is an enzyme that acts as a serine protease inhibitor. It mainly inhibits thrombin playing a significant role in the regulation of coagulation. HC-II has an approximate molecular mass of 65 kDa and is primarily expressed in the liver and circulates in plasma. The HC protein is similar to another anticoagulant protein antithrombin but is specifically activated by dermatan sulfate.
- Biological function summary
Heparin cofactor II plays an essential role in maintaining hemostatic balance. It does not function as part of a larger complex but individually regulates thrombin activity. HC-II inhibits fibrin formation and platelet aggregation controlling thrombin’s role in the coagulation cascade. The activity of HC-II is important for keeping blood clot formation under control preventing excessive clot formation which can lead to vascular diseases.
- Pathways
Heparin cofactor II works in the coagulation pathway where it closely interacts with thrombin. Dermatan sulfate enhances its inhibitory effects on thrombin distinct from the action of heparin on antithrombin. Its regulation of thrombin makes it an important component in the hemostatic pathway maintaining normal circulation by balancing blood clotting and bleeding.
- Associated diseases and disorders
Heparin cofactor II is associated with thrombotic disorders including venous thromboembolism. Deficiency or malfunctioning of HC-II can lead to an increased risk of thrombosis due to inadequate inhibition of thrombin. Besides HC-II is associated with atherosclerosis where its interaction with dermatan sulfate could influence the progression of vascular lesions. The protein's role in modulating thrombin activity further connects it to coagulation factor V which can also impact thrombotic disease processes.
