  Working Principles
Click to ViewEach protein in a cell has its characteristic isoelectric point and molecular weight. The combination of these two characteristic enable the separation of almost each of the proteins in biological sample loaded in a gel matrix. Separation of proteins extracted from a biological sample happens in first by their isoelectric point, the first dimension, by the application of high voltage in a very high resistance pH-gradient gel matrix. Upon the completion of the first dimension, the proteins are then separated based on their molecular weight in SDS-PAGE gel system and detection/visualization of the proteins is accomplished by Coomassie brilliant blue staining (sensitivity of  100 ng) or silver staining (sensitivity of  10 ng)

  User Instructions
Separation of proteins for comparisons and detection of differentially expressed proteinsUsers need to specify the strips they plan to use. Preferably the isolated proteins must have been assessed for the quality as well as quantity using standard procedures so that the normalization with respect to protein samples to be separated using the 2D electrophoresis unit could be done. Also, enough protein samples must be available to run replicates. The procedure allows detecting the differentially expressed proteins but will not allow identification of the proteins.
