INNOVANCE Free PS Ag Assay
Easy, specific, and stable protein S antigen testing
The INNOVANCE® Free PS Ag assay is straightforward to use and easily fits into the laboratory routine. Meanwhile, the ISTH Guideline1 recognizes that free protein S antigen assays are the first-line diagnostic for protein S deficiency. The INNOVANCE Free PS Ag assay is a liquid latex reagent with high specificity for free protein S using two different antibodies that do not bind to protein S/C4b-binding protein complexes. In addition, this assay shows low interference with rheumatoid factors and heterophilic antibodies.
