Target data

Function

Factor XII is a serum glycoprotein that participates in the initiation of blood coagulation, fibrinolysis, and the generation of bradykinin and angiotensin. Prekallikrein is cleaved by factor XII to form kallikrein, which then cleaves factor XII first to alpha-factor XIIa and then trypsin cleaves it to beta-factor XIIa. Alpha-factor XIIa activates factor XI to factor XIa.

Notes

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.
