ProVir™, the world’s largest recombinant viral antigen collection, has been independently developed by Sino Biological.
The collection features a comprehensive collection of influenza antigens, an exclusive coronavirus catalog and many other hard-to-find viral proteins such as Cytomegalovirus, Ebola, RSV and Zika. The ProVir™ viral antigen bank includes more than 1,000 antigens from 90 virus types/subtypes and 350 strains.
It has been widely used across the world for vaccine development, immunodiagnostic assay, therapeutic antibody evaluation and infectious disease research.
Recombinant SARS-CoV-2 variants
The B.1.351 variant, the P.1 variant, the B.1.1.7 variants and the most recent variant B.1.617 first detected in India are of central concern due to their high prevalence.
A panel of recombinant RBD/Spike and nucleocapsid protein variants have been developed by Sino Biological to evaluate the efficacy of vaccination and the antibodies.
Recombinant antigens for influenza vaccine strains
The ProVir™ collection also includes 630+ ME, NA and HA antigens from more than 250 strains of influenza viruses, including vaccine strains and the pandemic strains. Recombinant flu antigens from all WHO-recommended vaccine strains in recent years are offered by Sino Biological.
Recombinant antigens for more infectious viruses
The ProVir™ collection includes antigens from a variety of viruses associated with many kinds of infectious diseases, ranging from common viruses such as HIV, HPV and RSV. It also includes viruses like Zika and Ebola.
Additionally, it features rare virus types like the vesicular stomatitis Indiana viruses and the Rift Valley fever.
