Our Protein C & Protein S category provides essential diagnostic assays and reagents for measuring these two critical regulatory proteins of the coagulation cascade, crucial for diagnosing thrombophilia and assessing thrombotic risk. We feature high-quality products from leading manufacturers including HYPHEN BioMed, Chromogenix, 5-Diagnostics, and QD-TECH, offering a variety of methodologies. The range includes Chromogenic Assays for the functional determination of Protein C (PC), such as BIOPHEN™ Protein C and Coamatic Protein C, as well as clotting assays for both Protein C and Protein S (PS), exemplified by the HEMOCLOT™ series. Additionally, we provide specific reagents like the LIAPHEN™ Free Protein S for antigen measurement and dedicated Chromogenic Substrates for Activated Protein C (APC) and Factor XIa, ensuring comprehensive and precise evaluation of this vital anticoagulant system.
