  • Molecular Characterization
    CTLA-4 Structure

    This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 41.8 kDa. The protein migrates as 48-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
CTLA-4 SDS-PAGE

Biotinylated Human CTLA-4, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

Immobilized Cynomolgus / Rhesus macaque B7-2, His Tag (Cat. No. CD6-C52H5) at 5 μg/mL (100 μL/well) can bind Biotinylated Human CTLA-4, Fc,Avitag (Cat. No. CT4-H82F3) with a linear range of 0.02-0.625 μg/mL (Routinely tested).

Protocol
CTLA-4 ELISA

Immobilized Biotinylated Human CTLA-4, Fc,Avitag (Cat. No. CT4-H82F3) at 1 μg/mL (100 μL/well) on Streptavidin (Cat. No. STN-N5116) precoated (0.5 μg/well) plate, can bind Ipilimumab with a linear range of 0.2-2 ng/mL (Routinely tested).

Protocol
CTLA-4 ELISA

Serial dilutions of Ipilimumab neutralizing antibody (1:2 serial dilutions, from 40 μg/mL to 0.019 μg/mL) were added into Human B7-1, Fc Tag (Cat. No. B71-H5259): Biotinylated Human CTLA-4, Fc,Avitag (Cat. No. CT4-H82F3) binding reactions. The assay was performed according to the above described protocol. Background was subtracted from data points before curve fitting.

Protocol
  • Background
    CTLA-4 (Cytotoxic T-Lymphocyte Antigen 4) is also known as CD152 (Cluster of differentiation 152), is a protein receptor that downregulates the immune system. CTLA4 is a member of the immunoglobulin superfamily, which is expressed on the surface of Helper T cells and transmits an inhibitory signal to T cells. The protein contains an extracellular V domain, a transmembrane domain, and a cytoplasmic tail. Alternate splice variants, encoding different isoforms. CTLA4 is similar to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T cells and may be important to their function. Fusion proteins of CTLA4 and antibodies (CTLA4-Ig) have been used in clinical trials for rheumatoid arthritis.
