Human IL-2 ELISA Standard,Invitrogen
Manufacturer: Invitrogen 29802965
DescriptionInterleukin 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. Description: Human IL-2 (also known as TCGF) is a ~15 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, 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 Human IL-2 ELISA Lyophilized Standard has been reported for use in the Human IL-2 Ready-Set-Go! ELISA kit (cat. 88-7025). Applications Tested: The Recombinant Human IL-2 ELISA Lyophilized Standard is intended to be used as a standard for the Human IL-2 Ready-Set-Go! ELISA kit (cat. 88-7025). Typically the standard is run in a series of 7 doubling dilutions from the ft.top ft. standard. Please refer to the Certificate of Analysis included with each ELISA set for instructions on the proper reconstitution and dilution of the lyophilized standard. Note: These are single-use vials. Use one time within 4 hours of reconstitution and discard. Reconstitute and dilute as suggested in the Certificate of Analysis or recovery may not be accurate.
