Glass and plastic surfaces can change the amount of peptide left in solution.
Surface effects are measurable
In an analytical study of several cationic peptides, researchers measured substantial adsorption to glass and plastic under their experimental conditions. The magnitude depended on the molecule and setup; it does not mean every peptide behaves identically.
Why a lab should care
Adsorption can make the measured concentration lower than the amount originally added. That can distort assay comparisons, especially at low concentrations or with high surface area. Record consumables and handling conditions in a study, and validate recovery for the actual peptide and analytical method rather than assuming a nominal concentration remains unchanged.
Container choice is an experimental variable, not merely packaging.
