anti-CD19 monoclonal antibody DI-B4

A low-fucosylated, humanized, IgG1 isotype, monoclonal antibody directed against the B-cell-specific membrane protein CD19 with potential immunostimulating and antineoplastic activities. Anti-CD19 monoclonal antibody DI-B4 binds to CD19, which may result in a strong antibody-dependent cellular cytotoxicity (ADCC) directed at CD19-expressing B cells but with minimal complement dependent cytotoxicity. DI-B4 contains low levels of fucose, which contributes to its enhanced ADCC activity. CD19 is a B-cell specific membrane antigen that is widely expressed during B-cell development and in all B-cell lineage malignancies.
