文摘

We developed a novel murine monoclonal antibody (mAb) against the C-terminal α-helix of the human von Willebrand factor A2, designated SZ-179. We showed that SZ-179 inhibited the interactions between VWF and ADAMTS13 and prevented the degradation of high molecular weight VWF multimers. Importantly, SZ-179 reduced the proteolysis of VWF-R1597W mutant by rADAMTS13 dose-dependently under native conditions. Our findings reveal a potential therapeutic target for bleeding disorders.
