Human Protein S (PROS) ELISA Kit

Protein S is a vitamin K-dependent plasma glycoprotein that serves as a cofactor for activated protein C in the natural anticoagulant pathway. The Assay Genie Human Protein S (PROS) ELISA Kit is supplied as a complete reagent set packaged for 96 assays, enabling quantitative measurement of Protein S in human plasma using a colorimetric assay principle. Each kit contains a pre-coated microplate, enzyme-conjugated detection antibody, calibrators, substrate, and buffers for building a standard curve. Investigators working on hereditary or acquired Protein S deficiency, venous thromboembolism, liver dysfunction, oral anticoagulant monitoring, or recurrent pregnancy loss rely on plasma Protein S quantification to evaluate anticoagulant capacity and overall coagulation balance.
