Tumor Necrosis Factor Alpha (TNF-α) is a multifunctional cytokine playing a pivotal role in inflammation, immune regulation, and cell signaling. The advent of High-Resolution TNF-α ELISA Detection Kits has revolutionized the quantification of this biomarker, enabling unprecedented sensitivity and specificity for both clinical and research applications.
What is TNF-α?
TNF-α is a pro-inflammatory cytokine primarily produced by macrophages and other immune cells in response to infection or injury. It mediates immune responses, apoptosis, and inflammation, making it a critical marker in diseases such as rheumatoid arthritis, Crohn’s disease, and cancer.
