From: The synovial proteome: analysis of fibroblast-like synoviocytes
Detail of an area of a two-dimensional gel of separated fibroblast-like synovial cellular proteins. The circled areas include the same species of proteins with different mobilities reflecting differences in isoelectric points due post-translational modifications: 215 spot series, vimentin; 237 spot series, beta actin; 278 and 280 spot series, lamin A/C; 279 spot series, caldesmon.
