Abstract
Summary: Crystalline neuraminidase prepared from Vibrio cholerae culture fluids by Ada, French & Lind (1961) was examined by moving boundary electrophoresis, analytical ultracentrifugation and diffusion. The various corresponding physical constants were obtained. The results indicated that, within the limits of the methods used, the crystalline protein was enzyme and was homogeneous.
