Sample Preparation for Protein Analysis
We optimize for your daily sample prep success
All samples require some form of preparation prior to study or analysis by mass spectrometry to remove detergents, reduce the complexity of the sample when focusing on specific proteins and/or tag proteins for identification/quantitation. Proper sample preparation is critical for mass spectrometry analysis, because the quality and reproducibility of sample extraction and preparation significantly impact results from mass spectrometry systems instruments. Sample preparation encompasses a wide range of techniques that includes offline lysate preparation, protein or peptide enrichment, sample clean-up and protein digestion.
For a combination of automated online sample preparation with integrated sample separation, view information on TurboFlow™ technology found in the sample separation area.
David Sarracino, Manager of Biomarker Workflows with Thermo Scientific discusses various sample preparation techniques designed to assist clinical translational researches improve their toughest challenges when working with biological samples. He reviews new products to improve sample clean up in both discovery and targeted quantitation biomarker analysis.
