MODEL RELEASED. Protein analysis. Technician using a proteomics imaging system to analyse a petri dish containing proteins isolated by SDS polyacrylamide gel electrophoresis (SDS-PAGE). SDS-PAGE is used to analyse the protein composition of cells and tissues. A sample has SDS (sodium dodecyl sulphate) added to it,which denatures it and applies an overall negative charge. It is then placed into a gel that has an electrical current passed through it,which separates the sample's proteins based on their differences in size and charge.
