A general procedure for HA is as follows, a serial dilution of virus is prepared across the rows in a U or V- bottom shaped 96-well microtiter plate. The most concentrated sample in the first well is often diluted to be 1/5x of the stock, and subsequent wells are typically two-fold dilutions (1/10, 1/20, 1/40, etc.).The final well serves as a negative control with no virus. Each row of the plate typically has a different virus and the same pattern of dilutions. After serial dilutions, a standardi… WebJun 9, 2012 · Hemagglutination inhibition (HI) technique was implemented to determine the antibody response for NDV (Beard, 1989), while, Enzyme-linked Immunosorbent antibody assay (ELISA) was employed for...
