Recombinant E. coli RecQ DNA Helicase Protein (Functional)

A recombinant protein supplied by Antibodies.com, expressed in Escherichia coli, targets the RecQ DNA Helicase and is provided as a full-length construct. It is validated for SDS-PAGE and functional studies, and is described as biologically active.

Purity is reported as greater than 90% by SDS-PAGE. The product is supplied as a liquid formulated in 20 mM Tris-HCl (pH 7.5) with 1 mM EDTA, 50 mM KCl, 1 mM DTT, and 50% glycerol. It is shipped at 4°C; on arrival it should be aliquoted and stored at -20°C, with freeze/thaw cycles avoided.

The protein exhibits DNA-dependent ATPase activity and functions as a helicase specific for various DNA structures, including branched forms and forks, and unwinds duplex DNA in an ATP-dependent manner. The product is intended for research use only.
