HemosIL* Free Protein S


Part Number: 20002700

HemosIL* Free Protein S

Intended use: Immunoturbidimetric assay for the quantitative determination of free Protein S in human citrated plasma on IL Coagulation systems.

Principle: Measures 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 Ca2+ 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.

Vials and volumes:

  • 3 x 4 mL C4BP Buffer (liq)
  • 3 x 4 mL C4BP Latex (lyo)
  • 3 x 2 mL Anti PS MAb Latex (lyo)
