IL-4 Monoclonal Antibody (8D4-8), eBioscience™, Invitrogen™
Mouse Monoclonal Antibody
Supplier: Invitrogen 14704981
Description
Description: The 8D4-8 antibody reacts with human interleukin-4 (IL-4), a 15-19 kDa cytokine secreted by Th2 cells. Applications Reported: The 8D4-8 antibody has been reported for use in capture of human IL-4 by ELISA and in intracellular staining for flow cytometric analysis. Applications Tested: The 8D4-8 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of human Interleukin-4 (IL-4) in combination with the biotinylated MP4-25D2 (13-7048) antibody for detection and recombinant human IL-4 (14-8049) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 1-4 μg/mL. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 500 pg/mL - 4 pg/mL should be included in each ELISA plate. The fluorochrome-conjugated 8D4-8 antibody is offered in 2 formats:- μg size: has been tested by intracellular staining for flow cytometric analysis. This can be used at less than or equal to 0.5 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.
Interleukin-4 (IL-4) is a pleiotropic, immune-modulatory cytokine produced by activated T cells, and serves as a ligand for interleukin 4 receptor. IL-4 has been found to have the broadest range of actions. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play an important role in mediating the immune regulatory signal of IL-4. The IL-4 gene, IL-3, IL-5, IL-13, and CSF2 form a cytokine gene cluster on chromosome 5q. In particular, IL-4 is located in close proximity to IL13 on the chromosome. Further, the IL-4 gene, IL13 and IL5 are found to be coordinated by several long-range regulatory elements over a 120 kilobase range on the chromosome. IL-4 delta 2 is a known splice variant of IL-4.Specifications
