Abstract
Abstract The reactions for determination of influenza neuraminidase are carried out in a series of bores in a titration plate, heating for the reaction being applied by a heater block with corresponding series of projecting heating elements immersible into the bores, with advantages in ease of mass investigation of different viruses and determination of the state of protection of a population against influenza.
