This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Interleukin-7 is a glycoprotein involved in the regulation of lymphopoiesis. Response of cells to IL7 is dependent on the presence of the interleukin 7 receptor (IL7R); the active receptor is an alpha/gamma chain heterodimer. The gamma(c) chain, which also associates with the interleukin-2 receptor, serves primarily to activate signal transduction by the IL7R complex, while the alpha chain of IL7R determines specific signaling events through its association with cytoplasmic signaling molecules.  The human and mouse sequence is nearly identical.  In humans, severe combined immunodeficiency is caused by genetic defects in IL-7 receptor. The tyrosine residue at the 449 position is a critical signaling site of the intracellular domain of IL-7 receptor. This site is rapidly phosphorylated by janus kinases after the IL-7 receptor is engaged. IL-7 Receptor Alpha Chain phospho Y449 Antibody is ideal for investigators involved in Cell Signaling, Signal Transduction and Immunology research.

Conjugated Peptide
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to residues near Y449 of mouse IL-7 protein.
This product was affinity purified from monospecific antiserum by immunoaffinity chromatography using phospho-peptide coupled to agarose beads followed by solid phase adsorption against non-phospho-peptide. This antibody is specific for mouse IL-7 protein phosphorylated at Y449.  A BLAST analysis was used to suggest cross-reactivity with IL-7 from human, mouse and rat sources based on 100% homology with the immunizing sequence.  Cross-reactivity with IL-7 from other sources has not been determined.

Application Details

This affinity purified antibody has been tested for use in ELISA, immunoprecipitation, and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 55 kDa in size corresponding to phosphorylated IL-7 by western blotting in the appropriate cell lysate or extract.  This phospho-specific polyclonal antibody reacts with mouse IL-7 pY449 and shows minimal reactivity by ELISA against the non-phosphorylated form of the immunizing peptide.
