Anti-CD124 antibodies are protein reagents that detect specific antigens. The CD124 antigen is another term for the human protein interleukin 4 receptor, encoded by the IL4R gene. The protein is a known receptor for both interleukin 4 and interleukin 13. Canonically, it has an amino acid length of 825 residues and a mass of 89.7 kilodaltons. Its subcellular localization is in the cell membrane and is secreted. It is expressed in many tissues, such as the bone marrow, tonsil, and appendix. The CD124 protein is a member of the Type I cytokine receptor protein family. Other alias names for CD124 include IL-4RA and IL4RA. Western Blot is a widely used application for the CD124 antibodies listed below. In addition, ELISA is also a common application.
