背景介绍 Foxp3, belonging to the forkhead family, is a master transcription factor that expresses exclusively in regulatory T cells, a subset of CD4+ T cells. Regulation of Foxp3 is critical for maintaining immunological tolerance. Over-expression of Foxp3 is known to suppress effector T cell activation. 产品介绍 Human Foxp3 luciferase reporter construct is stably integrated into the genome of Jurkat T- cells. The firefly luciferase gene is controlled by a human Foxp3 promoter and an enhancer-like conserved noncoding sequence upstream of the Foxp3 promoter.
