Canine Influenza Virus H3N2 Hemagglutination Inhibition

WebNov 15, 2024 · Compared with hemagglutination inhibition assays, mounting evidence suggest that microneutralization tests (MNTs) is a better choice for the evaluation of candidate pandemic influenza vaccines because they measure neutralizing antibody activity in cell cultures and are more sensitive in detecting H5 and H7. WebOn a 96-well plate, two hemagglutination units (HAU) of hCoV OC43/well were incubated with a semilogarithmic dilution series of test samples for 10 minutes at RT. A suspension of chicken red blood cells (RBC; 1%, v/v in phosphate-buffered saline [PBS]) was added to each well to allow hemagglutination (HA) of RBC by the virus for 1.5 hours at 4°C. イラレ 版面 https://bablito.com
