      Interleukin-2 / IL-2抗体

    Interleukin-2 / IL-2抗体产品信息免疫原 : Recombinant Rat Interleukin-2 / IL-2 protein (Catalog#80075-RNAE)

    Antibody Type : Mouse Monoclonal Antibody ( Mouse mAb Service Platform )
    克隆号 : 10
    抗体宿主 : Mouse IgG2b
    缓冲液 : 0.2 μm filtered solution in PBS, 5% trehalose may be added in some batches. Please read the hardcopy of COA or contact our customer service to confirm the formulation.
    制备方法 : This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Rat Interleukin-2 / IL-2 (rR Interleukin-2 / IL-2; Catalog#80075-RNAE; P17108; Ala21-Gln155). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
    Interleukin-2 / IL-2抗体 Background
    Interleukin-2, also known as T-cell growth factor, TCGF, Aldesleukin and IL2, is a secreted protein which belongs to theIL-2 family. Interleukin-2 / IL-2 was the first interleukin molecule to be discovered. Interleukin-2 / IL-2 molecule was first purified to homogeneity by immunoaffinity chromatography by Kendall Smith and his team at Dartmouth Medical School. Interleukin-2 / IL-2 was also the first cytokine shown to mediate its effects via a specific IL-2 receptor, and it was also the first interleukin to be cloned and expressed from a complementary DNA (cDNA) library. Interleukin-2 / IL-2 was designated number 2 because Smith's data at the time indicated that IL-1, produced bymacrophages, facilitates IL-2 production by T lymphocytes (T cells).
    Interleukin-2 / IL-2 is produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Interleukin-2 / IL-2 is normally produced by the body during an immune response. When environmental substances (molecules or microbes) gain access to the body, these substances (termed antigens) are recognized as foreign by antigen receptors that are expressed on the surface of lymphocytes. Antigen binding to the T cell receptor (TCR) stimulates the secretion of Interleukin-2 / IL-2, and the expression of IL-2 receptors IL-2R. The IL-2 / IL-2R interaction then stimulates the growth, differentiation and survival of antigen-selected cytotoxic T cells via the activation of the expression of specific genes. Interleukin-2 / IL-2 can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells.
    The World Reference Standard for Interleukin-2 / IL-2 is produced by the National Institute of Biological Standards and Control in the UK. A recombinant form of Interleukin-2 / IL-2 for clinical use is manufactured by Chiron Corporation with the brand name Proleukin. It has been approved by the Food and Drug Administration (FDA) for the treatment of cancers (malignant melanoma, renal cell cancer), and is in clinical trials for the treatment of chronic viral infections, and as a booster (adjuvant) for vaccines. The use of Interleukin-2 / IL-2 in HIV therapy has been found to be ineffective.
