title: Two-dimensional gel electrophoresis characterization of the mouse leukocyte proteome, using a tri-reagent for protein extraction.
abstract: The use of "tri-reagents" allows the concomitant isolation of DNA, RNA, and proteins for a complete molecular characterization of biological samples. The aim of the current study was to perform the comparative evaluation of two-dimensional gel proteomes isolated with or without a tri-reagent protein extraction step before dissolving the samples in the first-dimension electrophoresis buffer. We conclude that the use of tri-reagents increases the amount of protein extracted from the sample. Furthermore, an average of 301 +/- 3.6 spots were found in gels from both sample preparation methods, whereas 71.7 +/- 8.1 and 49.7 +/- 2.3 spots were uniquely seen in tri-reagent and non-tri-reagent samples, respectively.
