Technozym® ADAMTS-13 Fluorogenic Activity/Antigen
$0.00
Technozym® ADAMTS-13 ELISA is a Fluorogenic ELISA kit for the determination of ADAMTS-13 activity and 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.

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.
