Inflammation is a physiological process in response to tissue damage resulting from microbial pathogen infection, chemical irritation, and/or wounding. During both acute and chronic inflammatory processes, various types of leukocytes, lymphocytes, and other inflammatory cells are activated and attracted to the inflamed site by a signaling network involving a great number of growth factors, cytokines, and chemokines. 
Signosis has developed a plate-based array for profiling 20+ inflammation-regulated genes. By using this assay, researchers are able to compare gene expression in up to three samples on a single microtiter plate.
