CTLA-4 Antibody (MA5-23842) in Neu
Neutralization of CTLA-4 in Jurkat human acute T cell leukemia cell line. Samples were incubated in CTLA-4 monoclonal antibody (Product # MA5-23842). Recombinant Mouse CTLA-4 Fc Chimera inhibits Recombinant Human B7-1/CD80 Fc Chimera induced IL-2 secretion in the Jurkat human acute T cell leukemia cell line in a dose-dependent manner (orange line), as measured by the Human IL-2 Quantikine ELISA Kit. Inhibition of Recombinant Human B7-1/CD80 Fc Chimera (3 µg/mL) activity elicited by Recombinant Mouse CTLA-4 Fc Chimera (1 µg/mL) is neutraliz... View More

Product Specific Information
In direct ELISAs, this antibody does not cross-react with recombinant mouse (rm) CD28, recombinant human CTLA-4, rmICOS, or rmPD-1.
Reconstitute at 0.5 mg/mL in sterile PBS.
Endoxin level is <0.10 EU per 1 µg of the antibody by the LAL method.
Target Information
CTLA4 (Cytotoxic T-Lymphocyte Antigen 4) is a CD28-family receptor expressed on mainly CD4+ T cells. It binds the same ligands as CD28 (CD80 and CD86 on B cells and dendritic cells), but with higher affinity than CD28. However, in contrast to CD28 which enhances cell function when bound at the same time as the T cell receptor, CTLA4 inhbits the T cell and prevents it from functioning. Intracellular CTLA4 is also found in regulatory T cells and may be important to their function.
