COMATIC® PROTEIN S - FREE
Automated latex ligand immunoassay for the quantitative determination of free Protein S (PS) in human citrated plasma on automated instruments. Two forms of Protein S are present in plasma: free Protein S (40%), and Protein S linked to the complement C4b-binding protein (C4BP) (60%). Only free Protein S has functional cofactor activity.
Measurement Principle
The presence of free Protein S in the sample is measured as the increase of turbidity produced by the agglutination of two latex reagents. Purified C4BP adsorbed onto the first latex reagent reacts with a high affinity for free Protein S of patient plasma in the presence of Ca 2+ ions. The free Protein S adsorbed on the C4BP latex triggers the agglutination reaction with the second latex reagent, which is sensitized with a monoclonal antibody directed against human Protein S. The degree of agglutination will be directly proportional to the free Protein S concentration in the test sample and is determined by measuring the decrease of the transmitted light at 405 nm caused by the aggregates.
