Seasonal flu is a common infectious disease of the respiratory tract caused by influenza viruses. There are four types of influenza viruses, influenza type A, B, C, and D. The A and B types are of most interest to the medical community because they are the culprits for seasonal epidemics. Occasionally, influenza A, like the A/California/04/09 (H1N1) and A/Hong Kong/1/1968 (H3N2), can even cause global pandemics. Vaccination is the most effective way to prevent flu infection. Each year, several different flu strains are selected as vaccine strains based on surveillance data of the recent isolates, and the performance of the vaccines from the previous season. In recent decades, most vaccines are trivalent or quadrivalent, including one H1N1, one H3N2, and the Yamagata and Victoria type flu B. Sino Biological offers recombinant Flu antigen products under its ProVir® viral antigen collection. The product line covers Hemagglutinin (HA), Neuraminidase (NA), and Nucleoprotein (NP) proteins, from all WHO-recommended vaccine strains in recent years. These antigens can be used to analyze vaccine-induced antibody response. In addition, Sino Biological also develops a large collection of monoclonal antibodies against the flu antigens. These reagents can help facilitate relevant assay development.     Reagents for 2021-2022 Influenza Vaccine Strains A/Victoria/2570/2019 (H1N1)   A/Wisconsin/588/2019 (H1N1) Recommended for Egg-based (quadrivalent, trivalent) Vaccine Recommended for Cell- or Recombinant-based (quadrivalent, trivalent) Vaccine HA: 40787-V08H, 40787-V08H1 HA: 40787-V08H, 40787-V08H1 NA: 40785-V08B NA: 40785-V08B NP: 40774-V08B NP: 40774-V08B B/Washington/02/2019   B/Phuket/3073/2013 Recommended for Egg-based, Cell- or Recombinant-based (quadrivalent, trivalent) Vaccine Recommended for Egg-based, Cell- or Recombinant-based (quadrivalent) Vaccine HA: 40722-V08H HA: 40498-V08B NA: 40790-V08B NA: 40502-V07B NP: 40755-V08B NP: 40500-V08B A/Cambodia/E0826360/2020 (H3N2) Recommended for Egg-based, Cell- or Recombinant-based (quadrivalent, trivalent) Vaccine HA: 40789-V08H, 40789-V08H1 NA: 40784-V08B NP: 40778-V08B (Under Development)   Reagents for 2015-2021 Influenza Vaccine Strains 2020-2021 Vaccine Strains   2019-2020 Vaccine Strains   2018-2019 Vaccine Strains   2017-2018 Vaccine Strains   2016-2017 Vaccine Strains   2015-2016 Vaccine Strains   More Pandemic Threat Subtypes H1N1   H2N2   H3N2   H5N1   H7N2   H7N3   H7N7   H7N9   H9N2   H10N7     +1-215-583-7898 | order_us@sinobiological.com 1400 Liberty Ridge Drive, Suite 101, Wayne, PA 19087
