Description: Mouse IL-2 (also known as TCGF) is an ~17 kDa factor produced mainly by activated CD4+ T cells. IL-2 induces cell cycle progression of resting cells in an antigen non-specific manner and allows clonal expansion of activated T cells. IL-2 also acts on activated B cells, monocytes, NK cells, LAK cells, and on oligodendroglial cells in vitro. In addition, IL-2 plays a role in hematopoiesis, tumor surveillance and anti-inflammatory reactions, and hence is a central regulator of the immune response. Non-glycosylated IL-2 is biologically active.
Applications Reported: Recombinant mouse IL-2 is biologically active and can promote proliferation of mouse T lymphocytes in culture.
Applications Tested: The ED50 of this protein, as measured by CTLL-2 cell proliferation assay, is less than or equal to 175 pg/mL. This corresponds to a specific activity of greater than or equal to 5.7 x 10e6 Units/mg.
Source: E. coli expressed amino acids Ala21-Gln169 of mouse IL-2 accession # MMIL04.
Bioactivity: The ED50 of this protein, as measured by CTLL-2 cell proliferation assay, is less than or equal to 175 pg/mL. This corresponds to a specific activity of greater than or equal to 5.7 x 10e6 Units/mg.
Endotoxin: Less than 0.01 ng/ug cytokine as determined by the LAL assay. Purity: >98% as determined by SDS-PAGE.
Molecular Weight: The protein is a mixture of N-terminally methionylated and non-methionylated protein. Th DTT-reduced and non-reduced protein migrates as 18 kDa polypeptides on SDS-PAGE.
Storage and handling: For best recovery, quick-spin vial prior to opening. Use in a sterile environment.
Interleukin 2 (IL-2) is an immuno-modulatory cytokine that is important for the proliferation of activated T cells, differentiation of B cells, natural killer cells, monocytes and macrophages. IL-2 signals through the IL-2 receptor (IL-2R), a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL-4) and interleukin 7 (IL-7). The expression of the IL-2 gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a gene similar to IL-2 in mice leads to an ulcerative colitis-like disease that suggests an essential role of this gene in the immune response to antigenic stimuli.
