Abstract

In this study, we evaluated a concatenated low pH (pH 3) and high pH (pH 10) reversed‐phase liquid chromatography strategy as a first dimension for two‐dimensional liquid chromatography tandem mass spectrometry (“shotgun”) proteomic analysis of trypsin‐digested human MCF10A cell sample. Compared with the more traditional strong cation exchange method, the use of concatenated high pH reversed‐phase liquid chromatography as a first‐dimension fractionation strategy resulted in 1.8‐ and 1.6‐fold increases in the number of peptide and protein identifications (with two or more unique peptides), respectively. In addition to broader identifications, advantages of the concatenated high pH fractionation approach include improved protein sequence coverage, simplified sample processing, and reduced sample losses. The results demonstrate that the concatenated high pH reversed‐phased strategy is an attractive alternative to strong cation exchange for two‐dimensional shotgun proteomic analysis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
