5 Peptide Bioanalysis Sample Preparation Challenges (and how to overcome them!)

,

Scientists that have worked with peptides understand that peptide quantification can be challenging. One of the keys to successful peptide analysis is thorough and selective sample preparation. Sample preparation improves various aspects of chromatography and mass spectrometry analyses by utilizing solid phase extraction (SPE) to chemically separate different analytes and aid in removing the interfering…

Sample Prep before LC-MS Quantification of Peptides and Proteins

Confronting the challenge of sensitivity and sample loss As a relative newcomer to peptide and protein quantification coming from the small molecule world, I have learned that I need to think differently, and more creatively, to meet the challenges of these molecules.  As scientists with assay sensitivity goals, we sometimes have to take extra steps…
