Discover our extensive collection of research-grade antibodies,
rigorously validated for in vivo applications.
Precisely identify antibody-specific signals using matched isotype controls optimised for in vivo experimentation.
BiosimilarsInvestigate biological therapeutic mechanisms with cost-effective, research-grade biosimilar antibodies.
This non-therapeutic biosimilar shares the same variable regions as therapeutic Ofatumumab, ideal for research. Ofatumumab, a fully human IgG1 monoclonal antibody, targets CD20 (a B cell surface antigen present from pre-B to mature B cells, not plasma cells). By binding CD20’s unique membrane-proximal epitope, it induces B cell depletion via CDC and ADCC, suiting studies on B cell-mediated diseases, CD20 biology, and B cell depletion mechanisms in autoimmune disease and cancer.
