A rapid chromatographic method for quantitation of high molecular weight fibrinogen derivatives in plasma.

High molecular weight fibrinogen derivatives were precipitated from 3 ml of plasma by 0.88 M ammonium sulphate. The resuspended precipitate was analyzed by chromatography on a 2.5 x 30 cm glass bead Bio-Gel 5 M column by using a flow rate of 60 cm/hr and continuous effluent monitoring at O. D. 280 nm. Complete elution of fibrinogen occurred in 50 min. Elution profile was handled according to the chromatographic plate theory analysis. Results obtained by our method were not significantly different from those obtained by conventional chromatography.
