Bioluminescence
Bioluminescence — Light produced by a chemical reaction within a living organism, harnessed in reporter assays to measure peptide receptor activation in real time.
What Is Bioluminescence?
Bioluminescence is the production of light by living organisms through enzymatic oxidation of luciferin substrates. In peptide research, bioluminescent reporter systems (luciferase) are used in cell-based assays to measure peptide-induced gene expression, receptor activation, and signal transduction with extremely high sensitivity.
Peptide Research Applications
- Reporter gene assays: CRE-luciferase for cAMP, NFAT-luciferase for calcium, NF-kB-luciferase for inflammation
- BRET: Bioluminescence resonance energy transfer measures protein-protein interactions in living cells
- In vivo imaging: Luciferase-expressing tumors tracked non-invasively after peptide-drug treatment
