Sino Biological ProVir viral antigen bank

Sino Biological’s viral antigen bank is an extensive repository of recombinant viral antigens, featuring over 1300 antigens spanning 400+ strains.

Recombinant antigens are key reagents in infectious disease research, widely used in the context of antibody and vaccine development. In addition, high-quality antigens and antibodies are critical components in immunodiagnostic assays. Sino Biological is recognised as the first company to produce SARS-CoV-2 (COVID-19) viral antigens, having supplied the key spike protein reagents within 11 days in January 2020.

Sino Biological has now launched its recombinant viral antigen collection, ProVir, which includes over 1000 products from 100+ virus types/subtypes and 400+ strains. The product line features a wide range of high-quality recombinant proteins expressed in insect and mammalian cells, rigorously tested for their purity and bioactivity.

The portfolio includes the company’s coronavirus catalogue, a huge collection of influenza antigens from over 250 strains, and many other hard-to-find viral proteins such as RSV, Ebola and Cytomegalovirus. These reagents are specifically developed to help vaccine research and drug development.

Sino Biological products are distributed by Millennium Science.
