Abstract: Post-translational modification of proteins represents an essential mechanism that regulates the function and abundance of proteins and is critical to a wide variety of cell processes such as signal transduction, cell development and mitosis Post-translationally modified peptides are often present in low abundance and there is a need to characterize PTMs from limited starting material.
Here, we combine an improved immuno-enrichment methodology with high sensitivity trapped ion mobility mass spectrometry for improved sensitivity from less starting material.Summary: Here, we combine an improved immuno-enrichment methodology with high sensitivity trapped ion mobility mass spectrometry for improved sensitivity from less starting material.
