What was studied?
Chemically diverse quorum-sensing peptides were added to blood and evaluated across collection systems, handling conditions and storage periods.
What did the researchers report?
Measured stability depended on collection and handling choices. Some peptides degraded during long-term frozen storage despite low temperatures.
What are the limits?
Results for bacterial signaling peptides cannot define storage instructions for unrelated products. Sampling history and matrix-specific validation are necessary before interpreting concentration differences.
