A specific antibody population against human fibrinogen was isolated from a rabbit antiserum by affinity chromatography on fibrinogen-bound Sepharose gel. Using a sensitive competitive radioimmunoassay, the antibody population was found to recognize epitopes on native fibrinogen but crossreacted minimally with fibrinogen fragment D and an early plasmin-degraded fibrinogen A.alpha.-chain product, but not at all with fragment E or fibrinopeptides A and B. Fibrin monomers shared part of these epitopes. The antibody population crossreacted to a small extent with bovine, horse and baboon fibrinogens and not at all with fibrinogens from sheep, rat, pig, goat, guinea pig, dog and rabbit.
