PROCESS AND REAGENT FOR THE DETERMINATION OF BIOLOGICALLY ACTIVE HEPARINS IN PLASMA

摘要

A method for determining biologically active heparin comprising adding, in the absence of exogenous antithrombin III, a proteolytic enzyme selected from the group consisting of thrombin and factor Xa and a chromogen substrate for the enzyme to a heparin sample, measuring the dye released from the chromogen substrate and thus determining the amount of heparin present.
