Stago Launches Products for Measurement of Apixaban


The STA® – Apixaban Calibrator and Controls are highly specific, automation-ready products for determining the apixaban concentration in plasma when used in conjunction with the STA® - Liquid Anti-Xa assay (catalog #s 00311US and 00322US).  This method has been shown to have excellent performance with respect to sensitivity, dynamic range of the assay, inter-subject variability and coefficient of variation (CV).1,2,3 


Apixaban (Eliquis®), a synthetically derived drug from Janssen Pharmaceuticals and Bayer Healthcare, inhibits the blood coagulation cascade by its inhibitory action on coagulation factor Xa, resulting in inhibition of fibrin clot formation.2


The STA® – Apixaban Calibrator (catalog # 01112) contains 4 calibrator points, establishing a linearity range of 20 to 500 ng/mL.  In addition, the STA® – Apixaban Control (catalog # 01111) product contains two levels of control at the low and high end of the calibrator range.  The calibrator is stable for 4 hours and the control for 8 hours on board the STA line of automated coagulation analyzers.  In addition, the reconstituted control is stable at 2-8° C for 7 days.


Utilization of STA® – Apixaban Calibrator and Controls ensures high specificity and precision for apixaban determination.  In addition, barcoding of critical information on the reagent vials prevents transcription errors.


The apixaban controls and calibrators are labeled for research use only, and are not for use in diagnostic procedures in the United States and Canada.
