Factor XII is converted to it’s active form (XIIa) by the Coagulation Activator. Factor XIIa cleaves Prekallikrein into active Kallikrein which in turn cleaves the substrate releasing a colorimetric product. In the presence of the inhibitor, Factor XIIa is inactivated (XIIi) by the inhibitor and cannot activate Prekallikrein.

PK activity. Standard curve for pNA (n = 3) was used to estimate FXIIa activity in Normal Pooled Human Plasma and FXII-deficient Human Plasma (n = 3) (D). Assays were performed according to the kit protocol.
Reactivity data
Product details
The Factor XIIa Assay Kit (ab241041) utilizes the ability of factor XIIa to cleave a synthetic substrate to release p-Nitroaniline (pNA) which can be quantitatively measured by a colorimetric assay (OD405 nm). The kit is easy-to-use and can detect Factor XIIa (as low as 1 mPEU) from plasma samples. This kit also measures Factor XII. In the sample preparation, the FXII is converted to FXIIa by the FXII activator.
This product is manufactured by BioVision, an Abcam company and was previously called K994 Factor XIIa Activity Assay Kit (Colorimetric). K994-100 is the same size as the 100 test size of ab241041.
