An updated two‐dimensional gel database of rat liver proteins useful in gene regulation and drug effect studies

Abstract
We have improved upon the reference two‐dimensional (2‐D) electrophoretic map of rat liver proteins originally published in 1991 (N. L. Anderson et al., Electrophoresis 1991, 12, 907–930). A total of 53 proteins (102 spots) are now identified, many by microsequencing. In most cases, spots cut from wet, Coomassie Blue stained 2‐D gels were submitted to internal tryptic digestion [2], and individual peptides, separated by high‐performance liquid chromatography (HPLC), were sequenced using a Perkin‐Elmer 477A sequenator. Additional spots were identified using specific antibodies.
