Technozym® ADAMTS-13 Antigen
$0.00
Technozym ADAMTS-13 Antigen ELISA is a chromogenic test kit for the determination of ADAMTS-13 antigen concentration in human plasma. ADAMTS-13 is the enzyme that cleaves vWF under laminar flow conditions. A functional defect of this enzyme leads to the presence of higher molecular weight forms of vWF and thus to increased platelet aggregation, mainly in the microvasculature.
The importance of ADAMTS-13 antigen levels is unclear, but some data suggests that evaluation of antigen levels may provide useful information in research.

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.
