Description

This ELISA kit provides quantitative measurement of interferon-gamma (IFN-γ) in porcine samples, supporting immunological research where this cytokine serves as a central indicator of Th1-mediated cellular immunity. Because porcine IFN-γ concentrations can vary dramatically between baseline and immune-activated states — often spanning two orders of magnitude — this kit is designed to capture that full dynamic range within a single assay run.

Detection Range: The 6.25–400 pg/mL range covers both moderate constitutive IFN-γ levels in healthy pig serum and the elevated concentrations observed during active infection or post-vaccination recall responses, minimizing the need for serial dilutions across experimental groups.

Sensitivity: At 3.12 pg/mL, the kit detects the low-level IFN-γ secretion typical of unstimulated PBMC cultures, early innate responses, or subclinically infected animals where cytokine output has not yet peaked.

Sample Compatibility: Validation across serum, plasma, and tissue homogenates enables researchers to correlate systemic IFN-γ responses with localized production at infection sites — critical for mucosal immunology and vaccine challenge studies in pigs.

Assay Efficiency: The 1–5 hour protocol and 50–100 µL sample volume accommodate limited-volume collections from piglets and support same-day processing of multi-timepoint kinetic studies.

This kit is particularly suited for swine vaccine efficacy testing, PRRSV and ASF immune profiling, and porcine transplantation immunology research.

Function
(From Uniprot)

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.
