Used for rapid detection and quantification of human interferon-gamma (IFN-γ) in biological samples such as serum, plasma, or cell culture supernatants. Commonly applied in clinical research and immunology studies to assess immune responses, particularly in infectious diseases, autoimmune conditions, and cancer immunotherapy. The quick test format allows for faster results with minimal processing steps, making it suitable for high-throughput screening or point-of-care testing in research settings. Helps monitor T-cell activity and cytokine production in response to stimuli or treatments.
