Peptide therapies is a rapidly developing field with great potential, but successful downstream processing (DSP) is essential to bringing new peptides from discovery to commercialisation. Although the mainstays of peptide purification are advanced membrane filtering and preparative chromatography methods, the apparatus is but one component of the whole process. The choice of a reliable equipment manufacturer who serves as an authentic collaborator in process development and offers steadfast after-sales support is the real differentiator, which is sometimes disregarded. This strategic partnership has the power to make or destroy a peptide’s path to market; it goes beyond a simple vendor-client relationship.
The Associated Challenges of Peptide DSP
Peptide purification presents unique challenges:
- Complex Impurity Profiles: closely related impurities generated through synthetic routes
- Fragility and Degradation: gentle processing conditions are required as peptides are sensitive to pH, temperature, and shear forces
- Scalability: purity or yield needs to be uncompromised at pilot and commercial scales
- Scrutiny: rigorous regulatory norms needs to be met for consistency, purity and safety
Handling these challenges cannot be met just by equipment. It needs a deep understanding of the process and continuous support.
A Technical Overview of Peptide Downstream Processing:
Unlike larger proteins, peptides DSP is complex which presents unique challenges due to subtle differences in hydrophobicity, charge, and size. Common DSP techniques include:
Membrane Filtration:
- Microfiltration (MF) System: Ideal for clarification of peptide solutions
- Ultrafiltration (UF) System and Tangential Flow Filtration (TFF) System:
- Impurities Removal: Large molecular weight impurities and smaller molecules like salts can be removed through diafiltration.
- Concentration: Dilute peptide solutions can be concentrated, significantly reducing the volume for subsequent purification steps and improving the efficiency of downstream processes.
- Buffer Exchange: With diafiltration, efficient and gentle buffer exchange can be done, which is crucial for preparing peptides for chromatography or final formulation. This minimizes the risk of denaturation or degradation.
- Benefits: Low shear forces with high throughput, scalable to handle large volumes, and reusability of membranes contribute to lower operational costs.
- Nanofiltration (NF) System: For smaller molecular weight peptides, it can be used for concentration and desalting by diafiltration.
- Preparative Chromatography: The gold standard for high-resolution peptide purification.
- Reversed-Phase HPLC (RP-HPLC): For peptides having hydrophobicity, offering high resolution but high solvent consumption.
- Ion Exchange Chromatography (IEX): Charge-based separation, offering a complementary approach to RP-HPLC, particularly for peptides with distinct charge profiles.
- Size Exclusion Chromatography (SEC): Hydrodynamic size-based separation useful for removing aggregates or fragments.
- Multicolumn Countercurrent Solvent Gradient Purification (MCSGP): Continuous chromatography technique which improves productivity, reduces solvent consumption, and enhances yield.
The success can be achieved wrt quality, precision, and scalability of the equipment. However, just by having the best-in-class hardware with not be useful without the right support system.
The Imperative of Process Development (PD) Hand-holding
Process development forms a link between proof of concept at lab scale and production scale manufacturing. At this stage of purification development, methods are optimized for efficiency, yield, purity, and reproducibility. A trusted equipment manufacturer’s involvement in PD is invaluable for several reasons:
- Tailored Solutions, Not Just Products: Every peptide, every crude synthesis batch, is unique. A generic solution rarely achieves optimal results. A manufacturer involved in PD will work closely with your team to understand the specific impurity profile, desired purity, and economic targets.
- Sanitech Engineers’ Advantage: As highlighted on our R&D Process Development page, we offer comprehensive PD services. This includes “selection of suitable membranes,” “screening of resins,” and “process optimization and reproducibility studies.” They bring hands-on experience and capabilities with various approaches, from lab to pilot scale.
- Optimizing Parameters for Efficiency and Cost-Effectiveness: PD hand-holding helps in:
- Membrane Selection and Flux Optimization: Determining the optimal membrane type (MF, UF, NF) and pore size for efficient impurity removal and concentration without compromising peptide recovery. This includes optimizing transmembrane pressure and cross-flow rates.
- Chromatography Resin and Method Development: An experienced manufacturer can guide with their deep knowledge wrt resin selection and process optimization for maximal resolution and yield.
- Scale-Up Expertise: Sanitech Engineers clearly states their capability in developing process studies and data generation at lab scale minimizing costly troubleshoot at larger volumes
- Troubleshooting and Problem Solving: An experienced manufacturer providing PD support can provide deep insights, extending their knowledge of the equipment’s capabilities and limitations, to common bioprocessing challenges which reduces downtime and accelerates solutions.
- Reducing Time-to-Market: Sanitech Engineers provides a clear competitive advantage in accelerating the process development which reduces DSP costly, both in terms of lost revenue and extended R&D timelines.
The Value of a Dependable After-Sales Support
Membrane filtration and preparative chromatography systems require a heavy initial expenditure. Matching production schedules and controlling this investment require constant, optimal functioning. At this point, providing strong after-sales support is a must.
- Downtime: promptly diagnosing problems, supplying the required spare parts, and sending out skilled specialists thus reducing downtime
- Steady Performance: technical support, professional guidance, and preventative maintenance programs to keep your systems operating at their best.
- Support: engineers and specialists who are knowledgeable with the complex operations of the equipment.
- Spare Parts: a reliable manufacturer would ensure the availability of genuine spare parts, guaranteeing compatibility and optimal performance.
- Upgrade: protects your initial investment by guaranteeing that your systems stay up to date and compliant throughout their lives.
The Cost of a Poor Choice: Avoiding Pitfalls
Choosing an equipment manufacturer based solely on price can lead to significant downstream problems:
- Suboptimal Process Performance
- Extended Development Timelines
- Regulatory Headaches
- Frequent Downtime and High Maintenance Costs
- Loss of Batches
