 Human blood plasma fractionation yielded human serum albumin, serum gamma globulin, fibrinogen, thrombin, and blood group globulins.The fibrinogen and thrombin fractions were further combined during the War into additional products, including liquid fibrin sealant, solid fibrin foam and a fibrin film.Gamma globulins are found in Fractions II and III and proved to be essential in treating measles for soldiers.
