Diluent
Diluent — A substance used to dilute a concentrated solution, such as bacteriostatic water or sterile saline used for reconstituting lyophilized peptides.
What Is a Diluent?
A diluent is a liquid used to dissolve or dilute a lyophilized peptide before use. Proper diluent selection is critical for complete dissolution, peptide stability, and compatibility with the intended assay or application. The diluent must match the peptide's solubility requirements and the downstream use conditions.
Common Diluents
- Sterile water: For in vivo use. May need pH adjustment for acidic/basic peptides
- PBS: Physiological pH/osmolality. Suitable for most neutral peptides
- DMSO: For hydrophobic peptides. Prepare concentrated stock, dilute into aqueous
- Bacteriostatic water: Contains 0.9% benzyl alcohol. For multi-dose vial reconstitution
