Hydrodynamic properties of hemagglutinin isolated with bromelain from influenza virus were studied. The sedimentation constant determined by the method of analytical ultracentrifugation was 9.17±0.17S. The translation diffusion coefficient estimated by the method of optic mixing spectroscopy comprised (3.6±0.1)x10-7 cm2/s. A combination of both the constants in Svedberg's equation allowed calculation of the hemagglutinin molecular weight (approximately 230,000) which suggests a three-subunit structure of the molecule. The hydrodynamic diameter and friction ratio of an isolated molecule were calculated.
