Proteomics data in support of the quantification of the changes of bovine milk proteins during mammary gland involution

Here we provide data from three proteomics techniques, two-dimensional electrophoresis (2-DE) followed by identification of selected spots using MALDI-TOF, one-dimensional gel electrophoresis followed by LC-MS/MS analysis of gel slices (GeLC) and dimethyl isotopic labelling of tryptic peptides (DML), to quantify the changes in the repertoire of bovine milk proteins that occurs after drying off. We analysed skim milk and whey sampled at day 0 and either day 3 or day 8 after drying off. These analyses identified 45 spots by MALDI-TOF, 51 proteins by GeLC and 161 proteins by DML, for which the detailed data work-up is presented as three Excel files. The data supplied in this article supports the accompanying publication “Changes in the repertoire of bovine milk proteins during mammary involution” by Boggs et al.
