Manufacturing Process of Sparkpep Research-Grade Peptides
At Sparkpep, we are dedicated to producing high-quality research-grade peptides with exceptional purity and consistency. We ensuring stringent quality control at every stage.
High-Purity Water Usage
The process begins with the dissolution of peptides in WFI (Water for Injection) grade water, the highest purity standard available. This ensures a clean and contamination-free foundation for our products.
Excipients for Stability
To enhance stability, mannitol and sucrose are added as excipients. Mannitol serves as a bulking agent, while sucrose acts as a lyoprotectant, preventing degradation and aggregation throughout the freeze-drying and storage process.
Electrospray Ionization (ESI) and Sodium Introduction
During the Electrospray Ionization (ESI) process, the peptide solution is sprayed into a fine mist. At this stage, sodium ions are introduced and readily attach to the peptide molecules, facilitating ionization. This controlled ionization process plays a crucial role in enhancing the stability and characterization of the peptides.
Sterile Filtration
Following ionization, the peptide solution undergoes sterile filtration through a 0.22 µm PES (polyethersulfone) filter membrane to remove any potential contaminants and ensure a high level of purity.
Precise Vialing and Freeze-Drying
Once filtered, the solution is precisely dispensed into 3 mL vials. The vials are partially stoppered and placed into a freeze-dryer for a carefully controlled 36-hour lyophilization cycle, which consists of freezing at -40°C, primary drying via sublimation, and secondary drying via desorption.
At Sparkpep, we are committed to delivering research-grade peptides that meet the highest standards of quality and reliability.
