PRODUCT ANNOUNCEMENT

The Asserachrom® VIIa-AT product from Diagnostica Stago, Inc. (catalog #00491) is a new kit for the analysis of plasma circulating factor VIIa-antithrombin (FVIIa-AT) complex levels by the ELISA method, and can be run on any plate reader reporting at 450 nm. The kit is labeled for research use only, not for use in diagnostic procedures worldwide. This new product, the first of its kind is useful for looking at FVIIa-AT, and thus coagulation activation in prothrombotic disease states such as arterial and veneous thrombosis.

Unlike the FVIIa-TFPI complex, which stays bound to the endothelium, FVIIa-AT is released into the blood upon coagulation activation, making it a useful marker for this phenomenon. Use of this kit has been reported using plasmas from research subjects exhibiting hypercoagulability as a result of hemotological neoplasia (1) as well as factor VII deficiency (2). In addition, samples from patients on oral anticoagulation were examined using this kit (2). Other studies have also shown elevation of FVIIa-AT in antiphospholipid syndrome (3) and recent myocardial infarction (4).
