For Research Use Only. Not for use in diagnostic procedures. The 5-ELISA ADAMTS-13 Antigen kit is a two-site enzyme immunoassay for measuring ADAMTS-13 antigen in plasma or in any biological fluid where it must be tested. ADAMTS-13 is a metalloproteinase present in plasma at a concentration of about500-800 ng/mL. It cleaves high molecular weight von Willebrand factor polymers to a lower molecular weight, following its release into blood circulation from endothelial cells (released from Weibel-Palade bodies).
