Flg22 is a synthetic peptide used in research to study plant immune responses and the activation of innate immune signaling pathways.

Flg22 is a synthetic peptide that mimics a conserved epitope of bacterial flagellin, which is recognized by the plant immune system. This peptide is extensively used in plant biology research to investigate the mechanisms of innate immunity, particularly how plants detect and respond to pathogen-associated molecular patterns (PAMPs). Flg22 binds to the FLS2 receptor in plants, triggering a cascade of immune responses that lead to the production of reactive oxygen species (ROS), activation of defense-related genes, and the strengthening of cell walls. Researchers utilize Flg22 to explore the molecular interactions between plants and pathogens, and to develop strategies for enhancing crop resistance to diseases. FOR RESEARCH USE ONLY.
