Product details
While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.
Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.
The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Support team to know which antibody pair is suitable for this protein.

Biological function summary
PF4 plays an important role in modulating the immune response and coagulation processes. PF4 is not part of a stable protein complex but can interact dynamically with heparin on the surface of endothelial cells and glycosaminoglycans. It inhibits the action of heparin promoting clot formation and angiogenesis. PF4 also attracts and activates different types of leukocytes and can regulate inflammatory processes influencing how the immune system responds to injury.
Pathways
PF4 significantly interacts with both the coagulation and inflammation pathways. In the coagulation pathway PF4 acts to neutralize heparin-like molecules thereby enhancing thrombosis. It works closely with proteins such as thrombin and fibrinogen contributing to the blood clot cascade. Within the inflammatory pathway PF4's chemokine activity helps direct leukocytes to sites of tissue damage or infection linking it to cytokines and other chemokines that mediate immune responses.

General info
Function
Chemokine released during platelet aggregation that plays a role in different biological processes including hematopoiesis, cell proliferation, differentiation, and activation. Acts via different functional receptors including CCR1, CXCR3A or CXCR3B. Upon interaction with CXCR3A receptor, induces activated T-lymphocytes migration mediated via downstream Ras/extracellular signal-regulated kinase (ERK) signaling. Neutralizes the anticoagulant effect of heparin by binding more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Plays a role in the inhibition of hematopoiesis and in the maintenance of hematopoietic stem cell (HSC) quiescence. Chemotactic for neutrophils and monocytes via CCR1. Inhibits endothelial cell proliferation. In cooperation with toll-like receptor 8/TLR8, induces chromatin remodeling and activates inflammatory gene expression via the TBK1-IRF5 axis. In addition, induces myofibroblast differentiation and collagen synthesis in different precursor cells, including endothelial cells, by stimulating endothelial-to-mesenchymal transition. Interacts with thrombomodulin/THBD to enhance the activation of protein C and thus potentiates its anticoagulant activity.

Belongs to the intercrine alpha (chemokine CxC) family.
