Cholera autoinducer 1 (Cat No.:R030369) is a small-molecule signaling compound used by Vibrio cholerae in quorum sensing, a bacterial communication system that regulates group behaviors such as biofilm formation and virulence factor expression. CAI-1 is produced and secreted by the bacteria, and its extracellular accumulation allows V. cholerae to detect population density. Upon reaching a threshold concentration, CAI-1 binds to the CqsS sensor kinase, initiating a signaling cascade that alters gene expression. CAI-1 is essential for understanding microbial cooperation and is supplied for research into bacterial communication and pathogenesis.
