D-dimer is a specific product of the degradation of fibrin clots that results from the action of 3 enzymes: (a) thrombin, generated from the activation of the coagulation cascade that converts fibrinogen into fibrin clots; (b) activated factor XIII that cross-links fibrin clots by means of covalent bonds between fibrin monomers; and (c) plasmin, the ultimate enzyme of fibrinolysis that degrades cross-linked fibrin (1,–,3). Monoclonal antibodies (MoAbs)2 raised against specific epitopes on D-dimer react with cross-linked fibrin, but not with fibrinogen degradation products or non–cross-linked fibrin degradation products, thus ensuring high specificity of the D-dimer as a biomarker of fibrin formation and stabilization (4). Many types of D-dimer assays have been developed that can be broadly divided into 3 categories.

Principle of the Assay  
This kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. The purified anti- D2D antibody was pre-coated onto 96-well plates. And the HRP conjugated anti- D2D antibody was used as detection antibodies. The standards, test samples and HRP conjugated detection antibody were added to the wells subsequently, mixed and incubated, then, unbound conjugates were washed away with wash buffer. TMB substrates (A & B) were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the D2D amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of D2D can be calculated.
