Quantification

In this sandwich ELISA, Rat Interferon γ,IFN-γ in the sample is captured between a pre-coated capture antibody and a detection antibody. Signal intensity is proportional to analyte concentration. Quantification uses a standard curve fitted with Curve Expert software, covering 31.25 pg/mL-2000 pg/mL with a minimum detectable dose of 15.6 pg/mL.

For research use only (RUO). Not intended for diagnostic or therapeutic purposes. Validated in rat serum, plasma, cell culture supernates, tissue homogenates matrices only.
Description

This ELISA kit provides quantitative measurement of interferon-gamma (IFN-γ) in rat samples, supporting immunological research into Th1-driven immune responses, macrophage activation, and inflammatory signaling. Because IFN-γ is often measured across multiple compartments simultaneously — circulating levels, tissue microenvironments, and in vitro stimulation assays — this kit is designed to accommodate the full scope of such studies.

Detection Range: The 31.25–2000 pg/mL range captures rat IFN-γ concentrations from baseline circulating levels through the elevated concentrations seen in activated splenocyte supernatants or infection models. Samples from ConA- or antigen-stimulated cultures may require dilution, while unstimulated or naïve serum samples typically fall within range without concentration.

Function
Type II interferon produced by immune cells such as T-cells and NK cells that plays crucial roles in antimicrobial, antiviral, and antitumor responses by activating effector immune cells and enhancing antigen presentation. Primarily signals through the JAK-STAT pathway after interaction with its receptor IFNGR1 to affect gene regulation. Upon IFNG binding, IFNGR1 intracellular domain opens out to allow association of downstream signaling components JAK2, JAK1 and STAT1, leading to STAT1 activation, nuclear translocation and transcription of IFNG-regulated genes. Many of the induced genes are transcription factors such as IRF1 that are able to further drive regulation of a next wave of transcription. Plays a role in class I antigen presentation pathway by inducing a replacement of catalytic proteasome subunits with immunoproteasome subunits. In turn, increases the quantity, quality, and repertoire of peptides for class I MHC loading. Increases the efficiency of peptide generation also by inducing the expression of activator PA28 that associates with the proteasome and alters its proteolytic cleavage preference. Up-regulates as well MHC II complexes on the cell surface by promoting expression of several key molecules such as cathepsins B/CTSB, H/CTSH, and L/CTSL. Participates in the regulation of hematopoietic stem cells during development and under homeostatic conditions by affecting their development, quiescence, and differentiation.
