High-throughput proteomics processing of proteins in polyacrylamide in a multiwell format

J Proteome Res. 2007 Apr;6(4):1603-8. doi: 10.1021/pr060472y. Epub 2007 Mar 17.


Processing multiple protein samples from polyacrylamide at significant sensitivity represents a major chokepoint for raising the success rate in high-volume protein identification projects. A multiwell filterplate method for processing proteins in polyacrylamide was optimized for sensitivity using a protein standard. The results demonstrate this process to be a reliable and reproducible method over a range of gel loadings and suitable for the identification of proteins near the threshold of silver stain. This high-throughput manual method requires a minimum of specialized equipment, and can be performed disconnected from a proteomics infrastructure for the preparation of mass spectrometry-ready samples.
