Application examples

Application examples Western blot using anti-RuvB antibodies (E.coli)

Samples: 5 ng of recombinant RuvB protein (1)E. coli AB1157 crude extract (2); E. coli AB1157 lexA mutant crude extract (3) were separated on SDS-PAGE and transferred to a membrane, followed by incubation with a primary antibodies at 1: 3000 dilution, washes and incubation with secondary antibodies HRP conjugated. Reaction was visualized by chemiluminescnce following manufacture's recommendations.

Expression of RuvB is enhanced by lexA mutation.

Background RuvB protein of Escherichia coli forms a complex with RuvA protein and the complex promotes branch migration of Holliday junction at the late stage of homologous recombination and recombination repair. RuvB is a DNA motor protein which possesses the ATPase activity, activated by DNA and RuvA protein. RuvB in the absence of ATP, it predominantly occurs in a monomer form. In the presence of ATP, it forms dimer and hexamer depending upon the concentration. With RuvA and Holliday junction., it forms a double hexamer.
