Technical Data
F0047
Fen1 (FEN-1, Flap Structure-specific Endonuclease 1, MF1, Maturation Factor-1, RAD2, DNase IV)
Description:
FEN-1 (Flap EndoNuclease and Five prime Exonuclease) is a 42kD 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.

Application(s):
Suitable for use in Western Blot. HepG2, HeLa, T24 and HBL100 cell lysates have been tested. Other applications not tested.

Recommended Dilution:
Western Blot: 1:500-1:1000
Optimal dilutions to be determined by the researcher.

Positive Control:
Recombinant fusion protein

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20C or colder. Aliquots are stable for at least 12 months at -20C. 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.
