There is provided a means for sterilizing lactoferrin at a high temperature in a short time while maintaining the activity of the lactoferrin. The present technology provides a method for producing a lactoferrin-containing aqueous solution, including a sterilization step of heat-sterilizing a lactoferrin-containing aqueous solution, in which the total mass content of proteins other than lactoferrin is 1/12 or less of the mass content of lactoferrin, at a temperature of 100&#xb0; C. or more. The present technology also provides a lactoferrin-containing aqueous solution in which the total mass content of proteins other than lactoferrin is 1/12 or less of the mass content of lactoferrin, and which does not contain living bacteria.

A spout member including a base portion which is fixed to a bag body, a cylindrical portion which protrudes upward from the base portion, and a sealing portion which seals a front end of the cylindrical portion through a breakable thin portion is disposed between two sheets of film forming the bag body. A sealing chamber accommodating the cylindrical portion and the sealing portion is opened by tearing the two sheets of film along an opening assisting line. An opening assisting plate protruding to at least one of a left side and a right side of the sealing portion is disposed above the opening assisting line. A sandwiching reinforcement seal portion for reinforcing the two sheets of film by sealing inner surfaces thereof is provided between the opening assisting plate and the opening assisting line.

A magnetic write head having a shield structure that provides both a leading shield and side shielding function. The magnetic shield is separated from the sides and leading edge of the write pole by a non-magnetic gap layer that has a non-uniform thickness. The non-magnetic gap layer is thicker near the leading edge and thinner at the trailing edge. This allows for increased side field gradient near the trailing edge of the write pole and decreased write field loss at the leading edge of the write pole.

Magnetic recording head with non-conformal side shield gap

An agent for thermally stabilizing lactoferrin, which comprises a nucleic acid as an active ingredient, can be added to lactoferrin to impart thermal stability to lactoferrin. Thermally stabilized lactoferrin can be heat-sterilized at a pH value around a neutral pH value while keeping its activity.
