WebIn top-down proteomics, intact proteins or large fragments are ionized and analyzed by mass spectrometry (MS). Bottom-up proteomics analysis relies on peptides, which are generated by proteolytic digestion of protein samples. Due to the protein size limitation in top-down proteomics (<50 kD), bottom-up proteomics analysis is more commonly used. ... Web29. jan 2024 · Despite great progress in recent years, some challenges remain for top-down proteomics. The technique is relatively low-throughput as compared to bottom-up experiments, partly because of difficulties in automated liquid chromatography separation of intact proteins. However, useful alternatives are in development.
