Product overview
Human Thrombomodulin ELISA Kit (ab214029) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Thrombomodulin protein in cell culture extracts, cell culture supernatant, cit plasma, edta plasma, hep plasma, serum, urine, and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Thrombomodulin with 3 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
Human Thrombomodulin is a 557 amino acid type I transmembrane protein, consisting of six epidermal growth factor (EGF)-like domains and is highly glycosylated. Thrombomodulin is an important component in the anti-coagulation system by functioning as a cell surface receptor for thrombin, and has also been shown to play a role in anti-inflammation, cell adhesion, and proliferation. The Thrombomodulin - thrombin complex activates protein C and thrombin-activatable fibrinolysis inhibitor (TAFI); protein C degrades coagulation factors Va and VIIIa, which regulates thrombin resulting in inhibition of coagulation. The extracellular portion of Thrombomodulin has been shown to be released from the cell surface due to protein cleavage during vascular endothelial cell injury.

Function
Thrombomodulin is a specific endothelial cell receptor that forms a 1:1 stoichiometric complex with thrombin. This complex is responsible for the conversion of protein C to the activated protein C (protein Ca). Once evolved, protein Ca scissions the activated cofactors of the coagulation mechanism, factor Va and factor VIIIa, and thereby reduces the amount of thrombin generated. -
Tissue specificity
Endothelial cells are unique in synthesizing thrombomodulin. -
Involvement in disease
Defects in THBD are the cause of thrombophilia due to thrombomodulin defect (THR-THBD) [MIM:188040]. A hemostatic disorder characterized by a tendency to thrombosis.
Defects in THBD are a cause of susceptibility to hemolytic uremic syndrome atypical type 6 (AHUS6) [MIM:612926]. An atypical form of hemolytic uremic syndrome. It is a complex genetic disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, renal failure and absence of episodes of enterocolitis and diarrhea. In contrast to typical hemolytic uremic syndrome, atypical forms have a poorer prognosis, with higher death rates and frequent progression to end-stage renal disease. Note=Susceptibility to the development of atypical hemolytic uremic syndrome can be conferred by mutations in various components of or regulatory factors in the complement cascade system. Other genes may play a role in modifying the phenotype. -

Interpolated concentrations of native Thrombomodulin in human serum, and plasma samples.The concentrations of Thrombomodulin were measured in duplicate, interpolated from the Thrombomodulin standard curve and corrected for sample dilution. Undiluted samples are as follows: serum 25%, plasma (citrate) 25%, plasma (EDTA) 25% and plasma (heparin) 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Thrombomodulin concentration was determined to be 4.8 ng/mL in serum, 3.9 ng/mL in plasma (citrate), 3.8 ng/mL in plasma (EDTA) and 4.3 ng/mL in plasma (heparin).
