Abstract: The present invention aims to provide a method which enables efficient removal of impurities such as the host proteins from an influenza virus culture liquid by a simple operation, allowing separation and purification of an influenza virus antigen. The method of the present invention for producing a purified influenza virus antigen comprises the step of treating a sample containing an influenza virus with a surfactant, the step of bringing the sample after the treatment into contact with hydroxyapatite in the presence of the surfactant, and the step of recovering a hydroxyapatite-non-adsorbed fraction.

Abstract: A lubricant additive which comprises a succinimide compound or a boronization product thereof is advantageously used for preparation of a lubricant composition which can maintain the property of anti-shudder for a long time without decreasing the transmission torque capacity or the friction coefficient between metals.
