Non-Fucosylated Anti-Human CTLA-4 (AGEN 1884) Therapeutic Antibody (CAT#: BioBet-1725ZP) Datasheet

CTLA-4

cytotoxic T-lymphocyte associated protein 4

This gene is a member of the immunoglobulin superfamily and encodes a protein which transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.

This clone was generated using a stable CHO cell line with the FUT8 knockout gene. It was 100% non-fucosylated. In an in vitro cell-based ADCC assay, the afucosylated antibody clone showed significantly higher ADCC activity compared to its wild type version. The binding affinity of the non-fucosylated Fc variant antibody to Fc receptor is much higher than than the same antibody with fucosylated Fc. Robust and stable production of qualitative fully non-fucosylated therapeutic antibodies is achieved.
