Recombinant antigens are key reagents in infectious disease research, which are widely used in therapeutic antibody and vaccine development. Sino Biological has independently developed the world's largest recombinant viral antigen collection, ProVir™, which features an exclusive coronavirus catalog, a comprehensive collection of influenza antigens, and many other hard-to-find viral proteins such as Zika, RSV, Ebola, and Cytomegalovirus.

The ProVir™ viral antigen bank includes over 1,000 antigens from 90 virus types/subtypes and 350 strains, and has been widely used worldwide in infectious disease research, therapeutic antibody evaluation, immunodiagnostic assay, and vaccine development.

 

Recombinant SARS-CoV-2 Variants

The B.1.1.7 variants, the P.1 variant, the B.1.351 variant, and the most recent variant B.1.617 first detected in India are of particular concern because of their high prevalence. Sino Biological has developed a panel of recombinant RBD/Spike and nucleocapsid protein variants which can be used to evaluate the efficacy of the antibodies and vaccination.
