IL-2 Monoclonal Antibody (5H4), Invitrogen™

Description

MM101 targets IL-2 in ELISA, and WB applications and shows reactivity with mouse samples. The MM101 immunogen is recombinant mouse IL-2. MM101 detects IL-2 which has a predicted molecular weight of approximately 17 kDa. The MM101 mouse IL2 antibody (clone 5H4) has successfully been paired as the coating antibody in a sandwich ELISA with detection antibody MM102B (biotinylated conjugate of clone 1A12). Typical dilutions for sandwich ELISA include 1 μg/mL for coating and 0.125 - 0.25 μg/mL for detection. Antibody MM101 (clone 5H4) and biotinylated antibody MM102B (clone 1A12) have successfully been used in combination with recombinant mouse IL2 protein SMIL2 in ELISA applications. This antibody is produced by injecting Rat IgG secreting hybridoma cells into the peritoneum of mice. The resulting ascites is collected from the mice and the antibody is purified. This product has been tested for endotoxins by limulus amoebocyte lysate (LAL) assay and contains an endotoxin concentration of less than or equal to 10 endotoxin units per milligram (EU/mg).

Interleukin 2 (IL-2) is an immuno-modulatory cytokine that is important for the proliferation of activated T cells, differentiation of B cells, natural killer cells, monocytes and macrophages. IL-2 signals through the IL-2 receptor (IL-2R), a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL-4) and interleukin 7 (IL-7). The expression of the IL-2 gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a gene similar to IL-2 in mice leads to an μgcerative colitis-like disease that suggests an essential role of this gene in the immune response to antigenic stimuli.
