Construction of a monoclonal antibody against glabridin (2G4) and development of an enzyme-linked immunosorbent assay.

Introduction: Glabridin is a unique isoflavonoid found only in Glycyrrhiza glabra L. The pharmacological effects of glabridin are well established, especially for beauty- and wellness-related uses, such as antioxidant, anti-inflammatory, ultraviolet (UV) protection, and skin-lightening effects. Therefore, glabridin is often found in commercial products such as creams, lotions, and dietary supplements.
