  1. Cells are isolated from samples harvested from three different horses (1–3). The cell surface proteins were enriched with biotinylation, and the samples analyzed by mass spectrometry. Raw data was searched against the Equus caballus reference sequence database from Uniprot (UP000002281; May 16, 2017; 22,698 proteins) giving information about protein names, accession numbers, and gene names. Gene expression was used to verify the data. (+) indicates that the protein was identified in the sample, (−) indicates that the protein was not identified in the sample. (+/+) indicates identification both on the protein and gene level. (−/+) indicates no identification on the protein level, but identification on the gene level
