Antithrombin Xa
REF: 5502, 5507
Intended use
The Antithrombin Xa kit is a chromogenic assay intended for the quantitative determination of Antithrombin III (AT-lll) activity in human citrated plasma. This two-stage method utilises Factor Xa, added to a patient plasma dilution containing AT-lll in the presence of excess heparin and calcium. After an initial incubation period (stage 1), residual Factor Xa is determined with a Factor Xa-specific chromogenic substrate (stage 2). The residual Factor Xa activity is inversely proportional to the AT-lll concentration.
Main features
- Factor Xa assay
- Insensitive to Heparin Cofactor II
- Linear calibration from 7.5 - 150%
- Excellent open vial stability
