To the Editor:
We wish to announce the column chromatography module (MIAPE-CC) of the minimum information about a proteomics experiment (MIAPE) guidelines1, specifying the minimum information that should be provided when reporting the use of column chromatography in a proteomics experiment (Box 1). MIAPE-CC constitutes a further component of the MIAPE documentation system, developed by proteomics researchers working under the aegis of the Human Proteome Organisation's Proteomics Standards Initiative (HUPO-PSI; http://www.psidev.info/). Prior modules for mass spectrometry and gel electrophoresis have already been described in Nature Biotechnology2,3,4.
MIAPE-CC covers the use of columns for protein or peptide separation, with a view to supporting the sharing of best practices, validation of results, discovery of results and sharing of experimental data sets. For a full discussion of the principles underpinning this specification, please refer to the MIAPE 'Principles' document1. Specifically, the CC module covers the configuration of a column, the selection of a suitable mobile phase, the gradients employed during the column run, the collection of fractions and the associated detector readings. The guidelines request a brief description of the sample, sample processing before chromatography and the injection procedures. They do not address subsequent protein identification, chromatographic performance assessment procedures or the mechanisms by which data are captured, transported and stored. Note that where multidimensional chromatography is used, the module should be adhered to for each dimension, with specific fractions from one column being used as the input sample for another.
The full specification of the MIAPE-CC module is provided as Supplementary Table 1 and the most recent version can be obtained through the HUPO-PSI website. Note that subsequent versions of this document may have altered scope, as will almost certainly be the case for all the MIAPE modules. To contribute or to track progress to remain 'MIAPE compliant', browse the HUPO-PSI website (http://www.psidev.info/miape/).
