Peptide Separation by Two-dimensional Chromatography and Electrophoresis

Open access

Abstract

The separation of peptides from controlled proteolytic digests by two-dimensional paper chromatography and electrophoresis is finding wide application to studies of protein structure. With this method it is possible to compare digestion mixtures from different proteins and to detect differences as slight as the replacement of a single amino acid. Such differences are of importance in the comparison of homologous proteins from different animal and plant species, and in the study of genetically determined changes in protein structure, such as those resulting from a single gene mutation.

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.
