Factor XII Deficient Plasma

Description

Deficient plasma (lyophilized) for the assay of factor XII. All the clotting factors are present (constant and in the normal range, brought by the deficient plasma (lyophilized)), except for FXII, which is brought by the diluted tested plasma (lyophilized), and clotting is triggered with cephalin, activator and calcium (aPTT). FXII is the limiting factor and clotting time is inversely proportional to the concentration of FXII.

Intended use

Measurement of factor XII (FXII or factor hageman) activity in human citrated plasma using a clotting method, in the presence of cephalin, activator and calcium (aPTT reagent).For any in vitro protocol or research study where a source of human FXII deficient plasma is required.
