TAG |
C-Mouse Fc and 6×His Tag |
MOLECULAR CHARACTERIZATION |
CTLA-4(Gln36-Ser161) mFc(Pro99-Lys330) 6×His |
MOLECULAR WEIGHT |
The protein has a predicted molecular mass of 54 kDa after removal of the signal peptide. |
PURITY |
The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. |
FORMULATION & RECONSTITUTION |
Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution. |
STORAGE & SHIPPING |
Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature. |
BACKGROUND |
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. |
