Abstract
A micro-method based on Warren''s color reaction was developed for influenza neuraminidase and neuraminidase-inhibition assays. Extraction with butanol is omitted and the assay is performed in wells of special plexiglass trays where the reaction mixture is electrically heated to reading temperature. The result is read and compared to controls in the same tray. The microassay, being inexpensive, time-saving and easy to perform even in poorly equipped laboratories, is suitable for large-scale serological screening and identification of the neuraminidase antigen of isolates.
