About us
Peptide Manufacturer with 16+ Years of Experience
Delivering high-purity, custom and bulk peptides to clients worldwide,supplying products to well-known enterprises and famous video bloggers for a long time
Our peptide products are produced in a Class 100,000 sterile workshop, with microbial levels controlled to less than 100 CFU/m³ in the air, achieving vaccine-grade production standards.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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 Phase: The solution is cooled to -40°C, stabilizing the peptide structure.
Primary Drying: Water is removed through sublimation, eliminating the majority of moisture.
Secondary Drying: Any remaining bound water is removed via desorption, ensuring a stable, lyophilized peptide.
