Chromogenic activity assay kits and a highly sensitive ELISA for measuring tissue factor (TF) in plasma are now available from American Diagnostica Inc. The assays, which require micro-liters of sample to perform an analysis, demonstrate superior performance characteristics with regard to accuracy, precision, and specificity. Additionally, each test kit offers easy-to-store packaging with reagent lot-to-lot consistencies, extended shelf life, and reconstituted stabilities. Testing protocols for manual, semiautomated, or fully automated procedures also are available, as well as anti-TF antibodies and FITC-labeled antibodies for the study of TF on cell surfaces.
