Cytokine ELISA kits enable researchers to measure various cytokines, which include interleukins, interferons, chemokines, tumor necrosis factors, and bone morphogenic proteins. Cytokines are small signaling proteins defined as soluble molecules produced by one cell to act on another, initiating responses to processes such as immune response, infection, cancer, apoptosis, and development. Signaling is mainly carried out by binding to specific surface receptors, initiating intracellular signal cascades, and driving gene regulation. They are distinct from hormones in that multiple cell types may produce cytokines, and they are effective at much lower concentrations. ELISA Kits designed to detect and quantify specific cytokines are prominent and convenient tools in biomedical research. Use the filters on the left to select any desired ELISA kit attributes.
