Viral Antigen Product Line

Sino Biological Inc. will launch the world largest recombinant viral antigen collection, ProVirTM, on April 1st. The product line features a wide range of high quality recombinant proteins expressed in insect and mammalian cells. These products are rigorously tested for their purity and bioactivity. This unique portfolio includes over 800 products from 45 different types, 350 strains of viruses.

Recombinant antigens are key reagents in infectious disease research. They are widely used in the context of antibody and vaccine development. In addition, high-quality antigens and antibodies are critical components in immunodiagnostic assays.


Coronavirus Study

The ongoing COVID-19 is the third deadly coronavirus outbreak since the start of the 21st century, highlighting an urgent need to understand the general biology of coronaviruses. Sino Biological's ProVirTM collection carries a comprehensive panel of recombinant antigens from 2019 SARS-CoV-2, 2003 SARS-CoV, MERS, and other four common coronaviruses. These reagents are currently being used by over 200 companies and research institutions worldwide for antibody and vaccine development. In addition, some SARS-CoV-2 proteins are being used to manufacture NMPA-approved COVID-19 diagnostic kits in China.

Influenza Research

The COVID-19 pandemic has killed over 3,000 people, and is dominating the headlines of all news media around the globe. A much more common disease, influenza, is often overlooked even though it claims a startling 250,000-500,000 lives worldwide annually, as estimated by the WHO. The ProVirTM collection features 600+HA, NA, and ME antigens from over 250 strains of influenza viruses, including vaccine strains and the pandemic strains such as the 2009 swine flu (A/California/04/2009 (H1N1)). Development of another 150 antigens are currently underway. Sino Biological also carries antigen microarrays for influenza-related serology studies.

Ebola, Zika, HIV and more

The ProVirTM collection also offers antigens from a variety of other viruses ranging from Ebola and Zika to common ones like RSV, HPV, and HIV etc. It also features rare virus types such as the Rift Valley fever, Vesicular stomatitis Indiana viruses, among others.

Packaging and Scale-Up Production

Most products in the ProVirTM collection will be offered at a single package size of 100ug. For bulk (mg+) or special request orders, customized packaging will be available. The products can be supplied in either liquid or lyophilized format. Sino Biological is capable of providing viral antigens at gram level.

Price Changes for Current Products

A number of previously launched viral antigen products will be integrated into the ProVirTM collection. For some of the products, there are changes to the available pack size and list price. The new price will be implemented on April 1, 2020. Current customers of these products will receive an email notification on the details of the price changes. Sino Biological will continue to offer the old package sizes at the original price until April 15, 2020 as long as supplies last.
