Abstract: Proteins can be purified and concentrated from crude cell lysates using high-throughput, automated process control systems that use software application programs to instruct one or more processors, controllers, and actuators to control and/or monitor the operations of filtration, purification, and concentration modules in such systems. The high-throughput production of concentrated proteins can be enabled by filtering the lysates and using compressed, non-reactive gas to concentrate the purified proteins, rather than using more complex centrifugation techniques.
