Product Summary for Rat IFN-gamma Quantikine ELISA Kit

The Quantikine Rat IFN-gamma Immunoassay is a 4.5 hour solid phase ELISA designed to measure rat IFN-gamma levels in cell culture supernates and serum. It contains E. coli-expressed recombinant rat IFN-gamma and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate recombinant rat IFN-gamma accurately. Results obtained using natural rat IFN-gamma showed dose curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural rat IFN-gamma.

Background: IFN-gamma

IFN-gamma (Interferon-gamma) is the prototype proinflammatory cytokine and is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells. It plays a key role in host defense by promoting the development and activation of Th1 cells, chemoattraction and activation of monocytes and macrophages, upregulation of antigen presentation molecules, and immunoglobulin class switching in B cells. It also exhibits antiviral, antiproliferative, and apoptotic effects. In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation. IFN-gamma dimers signal through a receptor complex of two IFN-gamma R1 and two IFN-gamma R2 subunits.
