Factor XI Deficient Plasma

Description

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

Intended use

Measurement of Factor XI (FXI or factor rosenthal) 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 FXI deficient plasma is required
