31. In a final step, the fibrin fibers associate to form the fibrin gel. 32. It cleaves fibrin , fibronectin, thrombospondin, laminin, and von Willebrand factor. 33. This large burst of thrombin is responsible for fibrin polymerization to form a thrombus. 34. The ulcers may become covered by a yellowish white fibrin clot called a pseudomembrane. 35. Fibrin consists of the blood proteins fibrinogen and thrombin which participate in blood clotting.36. Fibrinogen is the protein component that forms fibrin , which in turn builds blood clots. 37. Factor XIII completes the cross-linking of fibrin so that it hardens and contracts. 38. Fibrin from different animal sources is generally glycosylated with complex type biantennary asparagine linked glycans.39. In fibrinolysis, a fibrin clot, the product of coagulation, is broken down. 40. It is also used in histology, for staining fibrin with the MSB Trichrome stain.
