Abstract
To determine the biological activity of protein S in a sample of human plasma, the suitably diluted sample is added to a substrate formed from plasma deficient in protein S, in which protein C is activated. The functionality of protein is evaluated by a coagulometric test using bovine thromboplastin with added calcium as the phospholipid source. Also disclosed is a kit for determining the activity of Protein S in a human plasma sample. The kit includes a first reagent which is human plasma deficient in protein S, a second reagent which contains an activator for protein C, and a third reagent which contains bovine thromboplastin.
