The Biorex Diagnostics Protein C and S assays are intended for the determination of Protein C/S activity in human plasma.
Proteins C and S help adjust the rate of blood clot formation. When a blood vessel or tissue is injured, the body initiates the coagulation cascade – a step by step process involving the activation of platelets and of up to 20 protein factors – which results in the formation of a stable blood clot. This clot prevents additional blood loss and protects the injury until it heals. Once it is no longer needed other factors break the clot down so that it can be removed.
