  • Title: Rapid extraction, radioiodination, and in vivo catabolism of 125I-labeled fibrinogen in the horse.
    Author: Coyne CP, Hornof WJ, Kelly AB, O'Brien TR, DeNardo SJ.
    Journal: Am J Vet Res; 1985 Dec; 46(12):2578-81. PubMed ID: 4083597.
    Abstract:
    Two methods were analyzed for the rapid extraction of equine fibrinogen from fresh plasma, using ammonium sulfate-sodium phosphate buffer. Fibrinogen from each of these 2 methods was then radiolabeled with 125I (half-life = 60.2 days, gamma = 35 keV), using monochloroiodine reagent. Mean protein-bound activity was 98.5% and mean clottable radioactivity was 94.1%. Radiolabeled fibrinogen administered IV to 15 horses had an overall mean (+/- SD) plasma half-life of 4.95 +/- 0.44 days.
