Alternative names:

CTLA4;CD152

Description:

Recombinant human CTLA-4 protein with C-terminal human Fc tag

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.

Molecular characterization:

CTLA-4(Gln36-Ser161) hFc(Glu99-Ala330)

Molecular weight:

The protein has a predicted molecular mass of 39.6 kDa after removal of the signal peptide.The apparent molecular mass of CTLA4-hFc is approximately 40-55 kDa due to glycosylation.

Tag:

C-Human Fc Tag

Expression host:

HEK293

Target:

CTLA-4

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:

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.
