METHOD OF ASSAYING ANTITHROMBIN III ACTIVITY

摘要

An improvement in the conventional antithrombin III activity assay, whereby sample dilution can be dispensed with and the effect of heparin cofactor II can be evaded. The assay method comprises effecting the reaction of antithrombin with thrombin in the presence of heparin and a salt which is used in a concentration of 0.2-0.9M instead of 0.2M which has been usual heretofore.
