FOPflash: Transfection grade T cell factor (TCF) reporter plasmid containing two full and one incomplete copy of the TCF binding site (mutated) followed by three copies in the reverse orientation, upstream of the Thymidine Kinase (TK) minimal promoter and Luciferase open reading frame. This plasmid serves as a negative control to TOPflash which contains wild type TCF binding sites.
TOPflash: Transfection grade T-cell factor (TCF) reporter plasmid containing two sets (with the second set in the reverse orientation) of three copies of the TCF binding site (wild type) upstream of the Thymidine Kinase (TK) minimal promoter and Luciferase open reading frame. FOPflash containing mutated TCF binding sites is also available as a negative control.
Applications:Assessment of Tcf activity in transfected cells using the TOPflash and the FOPflash reporter plasmids.
Storage and Stability:May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for 6 months at -20°C after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
