Wuxi BIOT Biology Technology Co., Ltd is a high-tech company, which integrates the R&D, production and sales together. BIOT built an advanced bio-chemical laboratory and a world-class ultra-purification facility for protein purification approved by SFDA in January of 2004. The whole manufacturing process is carried out in GMP environment strictly. The collagen of BIOT adopts international advanced bio-chemical extraction and purification technology. During the process of extracting collagen with bioactivities, all the hybrid proteins and other non-collagenous substances will be removed at the same time, ultimately getting high purity (>98.5%) collagen.The advantages of BIOT collagen are keeping triple helix structure of collagen with complete biologically activities, and good compatibility to human tissue, natural and stability, which are different from the hydrolysis of collagen protein without biological activity in the market.The highest purity of BIOT collagen can compete with any collagen product in the world, widely applied in medical, biomaterial, cosmetic and pharmaceutical industries as well as nutrition products.
