Human PROS1/Protein S ELISA Kit

PROS1 encodes Protein S, a vitamin K-dependent plasma glycoprotein that functions as a non-enzymatic cofactor for activated protein C within the anticoagulant cascade. Reduced circulating Protein S is implicated in venous thromboembolism, recurrent pregnancy loss, and inherited thrombophilia, so quantitative measurement of this approximately 70 kDa factor supports research into coagulation disorders, hemostatic balance, and PROS1 gene variants.

This immunoassay kit from Assay Genie is configured for in vitro quantification of human Protein S in cleared liquid biological specimens collected under standard anticoagulant protocols. It arrives as a single microplate pack with all reagents required to generate a standard curve and interpolate unknown specimen concentrations from absorbance data, suiting laboratory workflows in hematology research, vascular biology studies, and thrombosis-focused investigations. Each kit is intended for research use only and supports batch processing of experimental and reference specimens in parallel.
