IL2 Receptor alpha (IL2RA) Rabbit Monoclonal Antibody [Clone ID: AHT107]

CAT#: TA386157

Recombinant Anti-IL2R (Clone AHT107)

Specifications

Product Data

• Clone Name: AHT107
• Applications: ELISA, FC
• Reactivities: Human
• Modifications: This chimeric rabbit antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques.
• Host: Rabbit
• Isotype: IgG, kappa
• Clonality: Monoclonal
• Immunogen: BALB/c mice were immunized with human T lymphoblasts and spleen cells of the immunized animals were fused with X63-Ag8.653 mouse myeloma cells. The supernatants of the resultant hybridomas were screened by a proliferation inhibition assay (inhibition of the human T lymphoblast response to IL-2). Two of those (the clones AHT54 and AHT107) that produced antibodies which inhibited IL-2 dependent proliferation of human T lymphoblasts were selected, cloned and recloned.
• Specificity: AHT107 binds to a different epitope than IL-2. Suggested that determinant recognised by AHT107 is involved in formation of the high-affinity binding site of the p55 + p75 heterodimeric complex of the IL-2R in a way which does not disturb the interaction of the p55 molecule and IL-2, and that the high-affinity class of the IL-2R is responsible for mediating the growth signal at physiological concentrations of IL-2.
  
  This antibody has been used to create a chimeric antibody with a murine variable region and human constant region through the use of recombinant DNA techniques. This gave antigen specificity of the mouse, and immunogenicity, serum half-life, and effector functions of human antibodies. The chimeric antibody has been found to have a greater anti-proliferative effect on T lymphocytes (Rose 1991). AHT107 has been used in ELISAs for the detection of soluble human IL-2R in response to different forms of helminthic and protozoal infections (O. Josimovic et al. 1988).
