Fen1 (FEN-1, Flap Structure-specific Endonuclease 1, MF1, Maturation Factor-1, RAD2, DNase IV)

FEN-1 (Flap EndoNuclease and Five prime Exonuclease) is a 42kDa protein that functions as an endonuclease and cleaves branched DNA structures containing single-stranded 5' flaps or as an exonuclease on DNA nicks and gaps. FEN-1 endonuclease and exonuclease activities are stimulated by an association with proliferating cell nuclear antigen (PCNA) in the nucleus. FEN-1 is believed to have important roles in DNA replication and repair, and is required in cell-free DNA replication systems.\n\nPositive Control: HeLa, Raji and 3T3 cell lysates.\n\nApplications: \nSuitable for use in Western Blot. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. 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.
