Background
Monkey Interferon-gamma (IFN-γ) is a critical type II interferon that serves as a master regulator of innate and adaptive immunity; it is a dimerized cytokine produced predominantly by activated T lymphocytes and natural killer (NK) cells, and as the primary macrophage-activating factor, its central biological function is to promote cellular immunity against intracellular pathogens, particularly viruses and certain bacteria. Monkey IFN-γ exerts its effects by binding to a specific receptor complex, which leads to the upregulation of major histocompatibility complex (MHC) class I and II molecules to enhance antigen presentation, while also directly inhibiting viral replication, activating macrophages to kill phagocytosed pathogens, and promoting the differentiation of naïve T cells towards a Th1 phenotype. Due to the high genetic and physiological similarity between non-human primates and humans, monkey IFN-γ is widely used in preclinical research, particularly in vaccine development, infectious disease models (such as SIV), and immunotherapy studies, where its activity serves as a key biomarker for cellular immune responses.

Linearity
The concentrations of Monkey IFN-γ were measured and interpolated from the target standard curves and corrected for sample dilution.
#1 sample is undiluted samples are as follows: Monkey PBMC cells stimulated with 10ug/ml PHA for 5days (10%). The interpolated dilution factor corrected values are plotted. The mean target concentration was determined to be 8986.69 pg/mL in stimulated Monkey PBMC supernatant.
Linearity
#2 sample is undiluted samples are as follows: Monkey PBMC cells culture for 5days (100%). The interpolated dilution factor corrected values are plotted. The mean target concentration was determined to be 133.72 pg/mL in unstimulated Monkey PBMC supernatant.
To assess the linearity of the assay, the sample was spiked with high concentrations of Monkey IFN-γ in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
