peptidillä
Peptidillä is a Finnish term that translates to "with peptide" or "by peptide" in English. It is used in scientific and medical contexts, particularly in research and discussions related to peptide-based therapeutics, diagnostics, or other applications involving peptides. The prefix "peptidillä" indicates that a peptide is either the agent performing an action, the substance being used in a process, or the material with which something is characterized or treated.
For instance, in pharmaceutical research, a drug might be described as "peptidillä aktiivinen" (active with peptide)
