Used for rapid detection and quantification of human tumor necrosis factor-alpha (TNF-α) in biological samples such as serum, plasma, or cell culture supernatants. Widely applied in clinical research and diagnostic laboratories to assess inflammatory conditions, monitor autoimmune diseases like rheumatoid arthritis and Crohn's disease, and evaluate immune responses in infectious diseases or cancer. The quick test format allows for fast results with minimal processing steps, making it suitable for high-throughput screening and point-of-care research settings.
