Collagen (soluble bovine tendon type I) coated onto microtiter plates binds von Willebrand antigen (vW:Ag) in a dose-dependent manner. An ELISA test was set up with both antibody and collagen coated microtiter plates. Test specimens assayed were: 1) normal plasmas, 2) type I vW plasmas, 3) type IIa vW plasmas, and 4) factor VIII concentrates (KoateR,(More)

The radioenzymatic determination of plasma catecholamines with a modification of the method of da Prada & Zürcher ((1976), Life Sci 19, 1161-1174) is described. The several reaction steps were optimized with respect to the quantities of substrate and enzyme, and reaction time. There were particular methodological difficulties concerning the blanks, which(More)
