Interleukin ELISA kits are assays designed to detect the group of cytokines known as interleukins (ILs). There are many families of interleukins in humans, ranging from IL-1 to IL-36. Synthesized by many cells including CD4 T lymphocytes, macrophages, and endothelial cells, they have both pro-inflammatory and anti-inflammatory functions. They act as immunomodulatory and signaling molecules, activating many pathways and components in the immune system.
