Shenyang Watson Pharmaceutical Research Institute

Shenyang Watson Biotech is a specialized Chinese biotechnology company focused on the research, development, and industrialization of recombinant human proteins. Founded in 2003, the company is a pioneer in the use of the Pichia pastoris yeast expression platform to produce high-purity recombinant human serum albumin (rHSA). This technology provides a safe, animal-derived component-free alternative to traditional plasma-derived albumin, effectively eliminating the risk of blood-borne pathogen transmission. The company's products are designed for a wide range of applications, including use as pharmaceutical excipients, stabilizers in vaccine manufacturing, and therapeutic clinical treatments for hypoproteinemia. Shenyang Watson Biotech maintains advanced large-scale fermentation and purification facilities in Shenyang to support its pipeline of blood-substitute products.
