Zhongshan Bioengineering Co., Ltd. is a high-tech enterprise in the field of biomedicine with roots in Zhongshan for nearly 30 years, mainly producing and developing immunodiagnostic reagents for the detection of infectious diseases and tumor markers. In 2003, in the fight against SARS, it also played a positive role and was awarded the "Advanced Enterprise in the fight against SARS". After Guangdong Province launched a level 1 response to a major public health emergency, the company quickly organized research and development personnel to return online, began the development of novel coronavirus detection reagents, and declared Guangdong Province's emergency collection of novel coronavirus prevention and control scientific research projects. In 2020, our team designed a comprehensive temperature and humidity control solution for the workshop producing SARS-CoV-2 IgG/IgM antibody detection reagents for Zhongshan Bioengineering Co., LTD., from design solution to equipment installation, equipment commissioning, equipment acceptance and reagent production in just 15 days.
