01 / DESIGN
What was studied?
Time-course proteomics compared peptide formation and stability when measuring human hepatic transporters and membrane markers.
02 / FINDINGS
What did the researchers report?
Peptides separated into different digestion-and-stability patterns. Using selected signatures improved agreement among protein-quantification measurements.
03 / LIMITS
How should it be interpreted?
A weak signal may reflect inefficient digestion or peptide loss rather than low protein abundance. These selection rules concern the tested analytical workflow, not every peptide sequence.
