Collagen (also known as collagen) is the main component of the extracellular matrix (ECM) and is also the most abundant and widely distributed functional protein in mammals. Collagen accounts for 30-40% of the total protein in the human body, of which 70% is in the skin. It plays a variety of important biological functions, such as maintaining the elasticity of skin and muscles, enhancing the binding of calcium and bone cells, connecting bones and muscles, and maintaining corneal transparency.

Recombinant humanized type III collagen
The collagen currently supplied on the market can be mainly divided into animal-derived collagen and genetically recombinant collagen. Among them, genetically recombinant collagen has the characteristics of no potential animal-derived pathogenic factors, single ingredients, controllable quality, low immunogenicity and good scalability of production scale. It is recognized by consumers, the market is growing rapidly, and is gradually being promoted and applied to fields such as regenerative medicine, and has broad development prospects.
Recombinant humanized type III collagen is prepared by using recombinant DNA technology to genetically manipulate and/or modify the full-length or partial amino acid sequence gene encoding the required human type III collagen protein, and then using plasmids or viral vectors to introduce the target gene into host cells (bacteria, yeast or other eukaryotic cells, etc.), express and translate it into collagen or collagen polypeptides, and then extract and purify it.
Technological empowerment
Yaohai Novagen makes a strong breakthrough with recombinant type III humanized collagen

Breaking through technological innovation and adhering to the concept of empowering technology in the medical beauty industry, Yaohai Novagen relies on its parent company Yaohai Bio's mature and complete synthetic microbial high-throughput screening platform and recombinant protein synthesis expression platform to layout the development and research of medical beauty active raw materials and products. With solid molecular construction capabilities, rich process development experience, mature scale-up production and quality management capabilities, the first batch of recombinant type III collagen with independent intellectual property rights has been completed. Yaohai Novagen's recombinant type III humanized collagen is expressed in the Pichia yeast system. The sequence is a core functional segment with high activity, high hydrophilicity and potential triple helix activity selected from the amino acid sequence of human type III collagen. After high-throughput screening of hundreds of molecules, a molecule with 410 amino acids was finally determined. The maximum expression of this molecule in large-scale production can reach more than 50g/L, and the purity of fermentation expression can reach more than 90%; after purification, the purity is close to 100%, and the lowest endotoxin can be less than 0.005EU/mg; after identification, the molecule has a protein tertiary structure and has high activity in stimulating water ion channel proteins, repairing cell damage, and stimulating the expression of type I collagen.
