Sino Biological

Sino Biological is a Beijing-based life-sciences tools and services company that supplies recombinant proteins, antibodies, ELISA kits, and related reagents to academic, pharmaceutical, and biotechnology researchers worldwide. Founded in 2007 by Xie Liangzhi, the company grew out of China's expanding biotech ecosystem and built a catalogue focused on high-value targets used in basic research, diagnostics development, and therapeutic discovery. Its product lines include recombinant cytokines, growth factors, viral antigens, and a broad antibody portfolio, alongside custom protein and antibody production services. The company is perhaps best known internationally for its work on viral antigens and reagents. During the COVID-19 pandemic, Sino Biological supplied research reagents and services related to SARS-CoV-2, including spike protein and related antibody products, which raised its profile among global laboratories and vaccine developers. It also operates as a contract research organization (CRO), offering gene synthesis, protein expression, antibody development, and assay development services. Sino Biological is headquartered in Beijing and serves customers in China, the United States, Europe, and other research-intensive markets. It maintains overseas operations and distribution to support international clients. The company is publicly listed in China, trading on the Shenzhen Stock Exchange's ChiNext board under the ticker 301047, which gave it access to capital for expanding production capacity and service offerings. Its positioning sits at the intersection of life-science research reagents and biotech services: it competes with global reagent suppliers while leveraging cost and scale advantages from its Chinese manufacturing base. The brand is recognized in the research community for its large recombinant protein catalogue and for rapid response to emerging viral targets.

Sino Biological was founded in 2007 in Beijing by Xie Liangzhi, a researcher with experience in biotechnology and bioprocessing. The company was established to address the growing demand for recombinant proteins and antibodies used in life-science research, a market historically dominated by suppliers in the United States and Europe. From its base in Beijing, Sino Biological built a catalogue of recombinant proteins, including cytokines, growth factors, and viral antigens, and expanded into antibody production and related reagents. Over the following decade, the company developed contract research capabilities, offering services such as gene synthesis, protein expression, antibody development, and assay development. This dual model — catalogue products plus custom services — allowed it to serve both academic laboratories and biopharmaceutical companies. It also established a presence in international markets, with operations and distribution supporting customers in North America, Europe, and Asia-Pacific. Sino Biological gained wider international visibility during the COVID-19 pandemic, when it supplied research reagents and services related to SARS-CoV-2, including viral antigens and antibodies used by laboratories and vaccine developers. This period highlighted the company's role in rapid reagent development for emerging infectious diseases. The company is publicly listed in China, trading on the Shenzhen Stock Exchange's ChiNext board under ticker 301047. The listing provided capital to expand production capacity, research and development, and global sales infrastructure. Sino Biological continues to operate as a supplier of life-science reagents and CRO services, with its headquarters in Beijing and customers worldwide.
