Excipient Screening & Selection
Creative Biolabs is experienced in formulation development of vaccines including validated analytical assays and tools. We have established a comprehensive database and algorithm-based formulation platform which can help you explore the best formulations with high success rate and short timeline.
Vaccine Excipients
As more and more vaccines are developed, stabilization in processing and storage poses a major challenge to the pharmaceutical industry. Vaccines are inherently unstable and susceptible to degradation by several physical and chemical degradation mechanisms. Therefore, various excipients are required during processing and storage to stabilize biological agents and vaccines. Excipients are an integral part of vaccine candidates and play an essential role in the formulation development of vaccines. New therapies and powerful pharmaceutical products can be developed by selecting and using the right excipients. For proteins and vaccines, excipients have clear functional roles, including:
- Enhancing the solubility of the active substance
- Extending shelf life
- Maintaining proper pH and tension
- Maintaining the preferred stable conformation of the protein or vaccine
- Preventing aggregation or degradation of active substances
- Fillers, antioxidants or preservatives
Some commonly used pharmaceutical excipients in biologic and vaccine formulations including but not limited to:
| Buffers | Acetate, Succinate, Citrate, Histidine, Phosphate, Tris |
| Amino acids | Arginine, Aspartic acid, Glutamic acid, Lysine, Proline, Glycine, Histidine, Methionine |
| Stabilizer/Bulking Agents | Lactose, Trehalose, Dextrose, Sucrose, Sorbitol, Glycerol, Albumin, Gelatin, Mannitol, and Dextran |
| Surfactants | Tween 20, Tween 80, Pluronic F68 |
| Antimicrobial/Preservatives | Benzyl alcohol, m-cresol, phenol, 2-phenoxyethanol |
| Metal ions/Chelators | Ca²⁺, Zn²⁺, EDTA |
| Cyclodextrin based | Hydroxypropyl β-cyclodextrin |
| Others | Polyanions, Salts |
