Liwei Peptide Technology Platform

At Liwei Peptide, our technology platform is the foundation of our success in delivering high-quality peptides for various industries, including pharmaceuticals, cosmetics, biotechnology, and academic research. Our comprehensive platform integrates advanced peptide synthesis, purification, and lyophilization technologies, supported by proprietary innovations that set us apart in the global peptide market. This allows us to provide tailored solutions, ensuring the highest level of precision, purity, and performance for our clients.
Peptide Synthesis: Cutting-Edge Flexibility and Precision Our peptide synthesis capabilities are at the heart of our technology platform. Liwei Peptide employs both solid-phase peptide synthesis (SPPS) and liquid-phase peptide synthesis (LPPS) to create peptides of varying complexity, ranging from small bioactive peptides to large, multi-chain sequences.
Solid-Phase Peptide Synthesis (SPPS): SPPS is an essential technology in our platform, enabling us to rapidly synthesize peptides with lengths from 2 to 120 amino acids. This automated process ensures high efficiency and scalability, from small research quantities to large-scale industrial production. It also supports the synthesis of complex, modified peptides that meet specific research or therapeutic needs.
Liquid-Phase Peptide Synthesis (LPPS): For longer and more complex peptides that may be challenging to produce through SPPS, we utilize LPPS. This method allows us to maintain the highest quality while synthesizing peptides with intricate sequences, ensuring excellent structural integrity and biological function.
Our synthesis technology is enhanced by our ability to incorporate a variety of modifications into the peptides, such as acetylation, PEGylation, disulfide bond formation, isotopic labeling, and fluorescent tagging. These modifications expand the functional diversity of our peptides, making them suitable for a wide range of applications in drug development, cosmetics, diagnostics, and more.
Peptide Purification: Ensuring Superior Purity and Quality Achieving the highest levels of peptide purity is a priority at Liwei Peptide. Our purification technology platform is built around state-of-the-art high-performance liquid chromatography (HPLC) systems, including large-scale preparative liquid chromatography.
High-Performance Liquid Chromatography (HPLC): We utilize HPLC as the primary tool for separating synthesized peptides from impurities. With multiple Agilent and Waters HPLC systems in our facility, we ensure that each peptide batch meets the rigorous purity standards required by the pharmaceutical, cosmetic, and research industries. Our systems are capable of processing both small and large batches, making us adaptable to various production scales.
Large-Scale Preparative Chromatography: To support industrial-scale peptide production, we operate several 150mm+ preparative liquid chromatography units. These systems are optimized for high-throughput processing, allowing us to purify large quantities of peptides efficiently. Our patented peptide separation technology further enhances the purity and yield of our products, giving us a competitive advantage in the global peptide market.
Through these technologies, we consistently deliver peptides with purity levels of up to 99%, ensuring that our products meet the most stringent requirements for both research and commercial applications.
Lyophilization (Freeze-Drying): Stability and Longevity Our technology platform also includes advanced lyophilization systems, which are essential for stabilizing peptides for long-term storage and use. The lyophilization process involves the careful removal of water from peptide solutions, transforming them into stable, easily transportable powders.
Lyophilization Equipment: Our large-scale freeze-drying units are capable of handling high volumes, with an annual production capacity of hundreds of kilograms of lyophilized peptide products. This ensures that our peptides retain their biological activity, structural integrity, and potency over extended periods, making them ideal for use in pharmaceuticals, cosmetics, and research applications.
Customizable Processes: We customize the lyophilization process based on the specific properties of each peptide, ensuring optimal stability and performance. Our lyophilized peptides are easy to reconstitute, allowing them to be seamlessly integrated into various formulations and experiments.
Applications: A Platform for Innovation Our technology platform supports a diverse array of peptide applications across multiple industries:
Pharmaceuticals: We provide custom peptides for drug discovery, therapeutic development, and clinical research. Our platform allows us to produce peptides that are crucial in areas such as cancer therapies, antimicrobial peptides, and hormone treatments.
Cosmetics: Liwei Peptide is a leader in producing cosmetic-grade peptide.
