Accelerated recombinant protein purification process development automated, robotics-based integration of chromatographic purification and analysis

J Chromatogr A. 1998 Mar 6;798(1-2):73-82. doi: 10.1016/s0021-9673(97)01205-3.

Abstract

Recovery of recombinant proteins from endogenous, host molecules can be an experimentally intensive and time-consuming task. Often the time to analyze material during development of recovery procedures is the rate-limiting step. Nowadays, modern techniques and equipment are being specifically engineered to make this effort much more efficient. We present a case study to illustrate how a new, automation tool, designed for easy, systematic methods development, can be used for very rapid process and analytical optimization. This tool uses robotics to integrate process development with rapid LC-based analysis requiring no user intervention. The methods and procedures described can be generalized to any recombinant protein recovery campaign.
