VisuLizeÂ FIX Antigen Kit
The VisuLize FIX Antigen Kit is intended to quantitatively measure factor IX antigen in human plasma and factor concentrates. The biological importance of Factor IX is demonstrated in Hemophilia B (Christmas disease), an X-linked congenital bleeding disease resulting from a quantitative (low activity and low antigen) or qualitative (low activity and normal antigen) defect in Factor IX function. The congenital deficiency of Factor IX may be classified as severe (1% Factor IX activity), moderate (between 1 and 5% Factor IX activity) or mild (between 5 and 40% Factor IX activity). The laboratory diagnosis of Factor IX deficiency typically involves quantitative determinations of procoagulant levels i.e., functional activity of Factor IX.Ã‚Â¹ An ELISA for Factor IX antigen may be used in conjuction with functional assays in the area of gene therapy, assessment of Factor IX concentrates, determination of carrier status as well as distinguishing those patients with cross-reactive material (i.e., low functional activity but near normal antigen levels of Factor IX).
The VisuLizeÃ¢â€žÂ¢ FIX Antigen Kit is FDA cleared, Health Canada approved and CE marked for use as in vitro Diagnostic use.
