- 0.5mg/mL
- Receptor binding assays, low-density cell cultures
- 21–28 days
- Low (adsorption to vial walls exceeds aggregation)
- High-throughput screening where peptide cost per well is limiting
- 1mg/mL
- Standard in vitro assays, dose-response curves, cAMP functional assays
- 28–35 days
- Very low
- Default concentration for most melanocortin receptor research
- 1.5mg/mL
- High-density cell cultures, tissue penetration studies
- Low-moderate
- Applications requiring higher local peptide concentrations in media
- 2mg/mL
- Stability studies, accelerated degradation testing, formulation development
- 14–21 days
- Moderate (5–10% batch precipitation)
- Maximum recommended for aqueous storage; used primarily for analytical validation
- >2.5mg/mL
- Not recommended
- <14 days
- High (15–25% visible aggregation)
- Avoid unless using non-aqueous solvent systems with published protocols
