Protea Explorer protein sample preparation instrument integrates the various steps of protein sample preparation, from a single gel-spot to the mass spectrometer. Processing time is a few hours. The enclosed system permits a large menu of solution-based sample preparation applications, inherently reducing the problems of sample transfer losses and contamination due to handling. Software provides both a menu of standard control programs and the flexibility to develop custom applications. The system includes components that remove protein samples from gels then separates proteins by molecular weight. Downstream, there are components that allow the user to simultaneously electrospray and collect the same protein fractions for future use. Protea Biosciences, Inc.877-776-8321www.proteabio.com
