生物活性

UB-221 is a humanized IgG1 monoclonal antibody inhibitor targeting IgE. UB-221 significantly decreases IgE synthesis by stabilization of membrane-bound CD23 on B lymphocytes and inhibits FcԑRI-mediated basophil activation and degranulation. UB-221 reduces IgE level in cynomolgus macaques and human IgE (ε, κ)-transgenic (hIGHE-knockin) mice. UB-221 can be used for asthma and chronic spontaneous urticaria (CSU) research[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
