Catalogue number
ANT-481
Synonyms
GSE, CD152, IDDM12, CELIAC3, CTLA-4.
Type
Mouse Anti Human Monoclonal.
Introduction
CTLA-4 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.
Clone
PAT4F2AT.
Physical Appearance
Sterile filtered colorless solution.
Immunogen
Anti-human CTLA4 mAb, clone PAT4F2AT, is derived from hybridization of mouse F0 myeloma cells with spleen cells from BALB/c mice immunized with a recombinant human CTLA4 protein 36-161 amino acids purified from E. coli.
Ig Subclass
Mouse IgG1 heavy chain and Kappa light chain.
Purification Method
CTLA4 antibody was purified by protein-A affinity chromatography.
Formulation
1mg/ml containing PBS, pH-7.4, 10% Glycerol and 0.02% Sodium Azide.
Storage Procedures
For periods up to 1 month store at 4°C, for longer periods of time, store at -20°C.
