UB-221

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
