Recombinant CD25 antibody

Catalog No. ABIN7072444

Product Details anti-CD25 Antibody

Target: CD25 (IL2RA) (Interleukin 2 Receptor, alpha (IL2RA))

Antibody Type: Recombinant Antibody

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD25 antibody is un-conjugated

Application: Flow Cytometry (FACS), ELISA, Blocking Reagent (BR)

Purpose: Anti-IL2R [AHT107], Mouse IgG1, kappa

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.

Characteristics:

Original Species of Ab: Mouse

Original Format of Ab: IgG1

Purification: Protein A affinity purified

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.

Clone: AHT107

Isotype: IgG1 kappa

Application Details

Application Notes: 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).
