Title: Monoclonal antibodies to crosslinked fibrin degradation products (XL-FDP). I. Characterization and preliminary evaluation in plasma. Author: Gaffney PJ, Creighton LJ, Perry MJ, Callus M, Thorpe R, Spitz M. Journal: Br J Haematol; 1988 Jan; 68(1):83-90. PubMed ID: 3345297. Abstract: Monoclonal antibodies (mabs) were raised against X-oligomers, the earliest soluble fragments released from crosslinked fibrin (XL-FN), by the action of plasmin. Two of the mabs (NIBn 52 and NIBn 123) were monospecific for X-oligomers in that they showed no binding to fibrinogen, the plasmic fragments of fibrinogen (D and E) and non-crosslinked fibrin (X, Y, D and E), or the terminal digestion product of XL-FN, fragment DD-E. One other mab (NIBn 178) was panspecific for X-oligomers in that it exhibited a weak affinity for fibrinogen. The mabs were used to develop a two-site immunoradiometric assay (IRMA) and an enzyme-linked immunospecific assay (ELISA) which permitted the specific measurement of X-oligomers directly in plasma, rather than in serum. This immunoassay is a true assay of fibrinolysis as distinct from fibrinogenolysis and may be a potential aid in the diagnosis and evaluation of thrombosis. In preliminary studies, the assay detected low levels of X-oligomers in normal plasma and elevated levels in patients with disseminated intravascular coagulation.[Abstract] [Full Text] [Related] [New Search]
