Thrombomodulin (THBD) is a vascular endothelial membrane glycoprotein that functions as a central receptor in the protein C anticoagulant pathway. This endothelial receptor binds thrombin and converts it from a procoagulant enzyme into a key activator of the protein C pathway, thereby regulating coagulation and maintaining vascular homeostasis. Because thrombomodulin serves as the initiating receptor of the protein C pathway, Thrombomodulin Antibody is widely used in studies investigating thrombin regulation, endothelial anticoagulant signaling, and vascular hemostatic balance. Detection of this protein C pathway receptor in tissue sections and cellular models provides insight into how endothelial cells control coagulation and inflammatory signaling within the vascular system.
Thrombomodulin antibody, also referred to as THBD antibody and protein C pathway receptor antibody in the literature, recognizes a transmembrane receptor that forms a high affinity complex with thrombin on the endothelial cell surface. The thrombin-thrombomodulin receptor complex represents the critical molecular switch that activates the protein C pathway. Once thrombin binds thrombomodulin, its enzymatic activity shifts away from fibrin generation and toward activation of protein C, producing activated protein C that suppresses further coagulation signaling. Through this mechanism thrombomodulin functions as the principal receptor responsible for initiating the anticoagulant protein C pathway in vascular endothelial cells.
The thrombomodulin receptor contains several functional domains that support its role in the protein C pathway. The extracellular region of thrombomodulin includes epidermal growth factor-like domains that enable thrombin binding and facilitate activation of protein C. Formation of the thrombin-thrombomodulin complex dramatically accelerates conversion of circulating protein C into activated protein C, which then inactivates clotting cofactors Va and VIIIa. This anticoagulant signaling cascade represents one of the most important regulatory mechanisms preventing excessive clot formation while maintaining normal vascular function.
Because thrombomodulin acts as the endothelial receptor that initiates the protein C anticoagulant pathway, it is frequently studied in research focused on coagulation biology, vascular inflammation, and endothelial cell signaling. Alterations in thrombomodulin expression or function may influence thrombin activity, inflammatory signaling, and vascular stability. Investigating the distribution and regulation of this protein C pathway receptor therefore provides important insight into mechanisms controlling coagulation balance and endothelial homeostasis within the vascular system.
Clone THBD/1782 is a mouse monoclonal antibody designed to recognize thrombomodulin expression in research applications. This clone has demonstrated extremely clean specificity validation in large human protein microarray screening experiments, where selective binding to the intended THBD target was observed among thousands of human proteins. These results support the use of this Thrombomodulin Antibody for studies focused on the protein C pathway receptor responsible for thrombin-dependent activation of anticoagulant signaling in endothelial cells.
The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the Thrombomodulin Antibody / Protein C Pathway Receptor to be titered up or down for optimal performance.
Human recombinant partial protein corresponding to amino acids 69-194 was used as the immunogen for this Thrombomodulin antibody.
Store the Thrombomodulin antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
