At Liwei Peptide, we are dedicated to delivering top-tier peptide products by leveraging our advanced synthesis, purification, and lyophilization technologies. With years of expertise in the field, we offer a comprehensive suite of solutions tailored to meet the diverse needs of industries such as pharmaceuticals, cosmetics, biotechnology, and academic research. Here is an overview of the cutting-edge equipment and processes that define our capabilities:

Peptide Synthesis

Our peptide synthesis technology is a cornerstone of Liwei Peptide’s operations. We utilize both solid-phase peptide synthesis (SPPS) and liquid-phase peptide synthesis (LPPS) to manufacture peptides ranging from short sequences to complex, multi-chain peptides.
Solid-Phase Peptide Synthesis (SPPS): This technique allows us to efficiently synthesize peptides of varying lengths (up to 120 amino acids) with high purity and precision. By using state-of-the-art automated synthesizers, we can scale peptide production from small research quantities to industrial volumes, ensuring rapid and reliable delivery.
Liquid-Phase Peptide Synthesis (LPPS): LPPS is ideal for synthesizing peptides that are difficult to produce through SPPS, especially longer peptide chains. With our advanced LPPS equipment, we can create highly complex peptides while maintaining excellent purity and efficiency.
Our synthesis platform supports high-throughput production with a vast array of peptide modifications, such as acetylation, PEGylation, disulfide bond formation, and fluorescent labeling, offering versatility to meet specific client demands.

Peptide Purification

Following synthesis, purification is a crucial step to ensure the final peptide product meets the highest quality standards. At Liwei Peptide, we employ advanced purification technologies, including high-performance liquid chromatography (HPLC) and preparative liquid chromatography, to achieve exceptional purity levels (up to 99%).
HPLC Systems: Our facilities are equipped with multiple Agilent and Waters HPLC systems, capable of handling small to large batches of peptides. These systems allow us to fine-tune the separation of peptides from impurities, ensuring the final product meets stringent quality specifications.
Large-Scale Preparative Chromatography: For large-scale production, we use 150mm+ preparative liquid chromatography systems. These enable us to process large volumes of peptides efficiently while maintaining high yields and purity. Our proprietary patented purification technologies further enhance the purity and quality of our peptides, giving us a competitive edge in the market.

Peptide Lyophilization

Once purified, the peptides undergo lyophilization (freeze-drying), which is essential for stabilizing the peptides for long-term storage and use. Our cutting-edge lyophilization equipment ensures that peptides retain their biological activity and structural integrity after freeze-drying.
Lyophilization Systems: We have multiple large-scale freeze-drying units capable of producing hundreds of kilograms of lyophilized peptides annually. The freeze-drying process removes water from the peptides, transforming them into a stable powder form that is ideal for storage and transport.
Customization: Our lyophilization processes are highly customizable, allowing us to adjust parameters such as temperature and pressure to suit different peptide structures and applications. This results in peptide products with high stability, ensuring they perform effectively in their intended applications.
