FEN1 Antibody

FEN1 removes 5' overhanging flaps in DNA repair and processes the 5' ends of Okazaki fragments in lagging strand DNA synthesis. Direct physical interaction between this protein and AP endonuclease 1 during long-patch base excision repair provides coordinated loading of the proteins onto the substrate, thus passing the substrate from one enzyme to another. The protein is a member of the XPG/RAD2 endonuclease family and is one of ten proteins essential for cell-free DNA replication. DNA secondary structure can inhibit flap processing at certain trinucleotide repeats in a length-dependent manner by concealing the 5' end of the flap that is necessary for both binding and cleavage by the protein encoded by this gene. Therefore, secondary structure can deter the protective function of this protein, leading to site-specific trinucleotide expansions.The protein encoded by this gene removes 5' overhanging flaps in DNA repair and processes the 5' ends of Okazaki fragments in lagging strand DNA synthesis.

For short periods of storage (days) store at 4˚ C. For longer periods of storage, store FEN1 antibody at -20˚ C. As with any antibody avoid repeat freeze-thaw cycles.

FEN1 antibody can be used for detection of FEN1 by ELISA at 1:62500. FEN1 antibody can be used for detection of FEN1 by western blot at 1.25 μ g/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
