Applications: The Foxp3 promoter Jurkat reporter cell line is suitable for monitoring the transcription activity of Foxp3 in response to stimulant, and establishing cell-based screens for inhibitors that target specific Foxp3-stimulating molecules.
Background: 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.
Description: 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.
Format: Each vial contains 2 x 10^6 cells in 1 ml of 10% DMSO in FBS.
Host Cell Line: Jurkat
Mycoplasma Testing: This cell line has been screened using the MycoAlert™ Mycoplasma Detection Kit (Lonza, Cat. #LT07-118) to confirm the absence of Mycoplasma contamination. MycoAlert Assay Control Set (Lonza, Cat. #LT07-518) was used as a positive control.
Storage Stability: Store in liquid nitrogen immediately upon receipt.
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: BSL-1
