Abstract: The present invention contemplates a method of producing a recombinant protein comprising (a) fermenting a prokaryotic host cell wherein said prokaryotic host cell has been transformed with a nucleic acid encoding said recombinant protein, and (b) harvesting said recombinant protein under conditions where dO2 levels are greater than 0%, and (c) purifying said recombinant protein to a filtered bulk, wherein said filtered bulk does not contain detectable DHNA-recombinant protein adduct, as measured by an IEC assay at 310 nm.

Abstract: A mobile work platform is provided which includes four independently controllable wheels. The wheel speed as well as the motion of other components on the platform may be remotely controlled via continuously supplied or pre-programmed communications, thus negating the need for any type of control tether. The steering of the wheels, drive speed as well as the motion of a turret, boom and other components may be precisely and repeatably controlled using a system including a computer, transceivers, antenna, control boards and controlled hydraulic pumps and/or valves. The mobile work platform is controllable at distances up to five miles in an environment including buildings or other obstructions and up to twenty miles with a clean line of sight.
