Technozym® ADAMTS-13 Inhibitor
$0.00
Technozym® ADAMTS-13 Inhibitor ELISA is a test kit for detection of human autoantibodies (IgG) in serum or plasma against ADAMTS-13, the protease which is responsible for cleaving unusually large vWF (ULvWF). Most of these autoantibodies inhibit ADAMTS-13 activity and thus non-cleaved ULvWF accumulates in plasma. Technozym ADAMTS-13 INH assay makes it possible to research the difference between congenital (gene polymorphisms) and acquired (autoantibodies) when coupled to an activity assay.

Background
ADAMTS-13
ADAMTS-13 (a disintegrin-like and metalloproteinase with thrombospondin type 1 motif 13) is an enzyme (vWF-cleaving protease or vWF-CP) that specifically cleaves von Willebrand Factor (vWF) multimers.
