Recombinant DNA-directed RNA polymerase subunit beta (rpoB) , partial

Recombinant DNA-directed RNA polymerase subunit beta (rpoB) , partial can be expressed and purified from different hosts. E. coli and yeast offers the best yields and shorter turnaround times. Expression in insect cells with baculovirus or mammalian cells can provide many of the posttranslational modifications necessary for correct protein folding or retain the proteins activity.
