Considerations for Selecting the Optimal Stationary Phases for Proteomic Trap-and-Elute Nanochromatography

18 Dec 2017

This white paper reviews various experimental parameters that influence the chromatographic performance of a trap-and-elute nanoLC method. The most important step in the method development process is to select an appropriate column and trap pair that maximizes chromatographic resolution so that the method is capable of thoroughly identifying proteolytic peptides.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.NanoLCNano LC is a nano scale liquid chromatography technique typically used for proteomic applications. The nano refers to the very low flow rate of the mobile phase in the system. The advantage of nanoLC is its high sensitivity. Often the system is integrated with a mass spectrometer in nano LC-MS or nano LC-MS/MS. When using nanoLC equipment consider column choice, software and accurate and precise flow rate control.Chromatography Method DevelopmentChromatography method development is the process of designing and optimizing chromatographic techniques to separate and analyze complex mixtures. This includes selecting appropriate stationary and mobile phases, determining flow rates, and optimizing detection methods.
