摘要:
The present inventors generated modified antibodies in which several Fc domains are linked in tandem to the C terminus of the heavy chain, and modified antibodies in which Fc domains are linked in tandem via spacers, and measured the affinity for Fc receptors, CDC activity, and ADCC activity. A previous report indicated that CDC activity is not enhanced by linking multiple Fcs. However, the modified antibodies of the present invention exhibited enhanced ADCC activity. The methods of the present invention enable provision of antibody pharmaceuticals having a marked therapeutic effect.

A method of manufacturing a tape-formed oxide superconductor, in which a tape-formed wire material (6) is extended between a pair of reels (5a and 5b) . Besides, a reactive gas is supplied from the gas supply ports of a reactive gas supply pipe (3a) vertically to the upper side film surface of the tape-formed wire material (6), so as to react the film body of this tape-formed wire material into a superconducting layer, while at the same time, a gas after the reaction is discharged from the gas discharge ports of discharge pipes (4a and 4b) for discharging the gas after the reaction. Likewise, the reactive gas is supplied via gas supply pipe (3b) vertically to the lower side film surface of the tape-formed wire material (6), so as to react the film body of this tape-formed wire material into a superconducting layer, while at the same time, the gas after the reaction is discharged from the gas discharge ports of discharge pipes (4c and 4d) for discharging the gas after the reaction. Even when the tape-formed wire material (6) is large in area, the tape-formed oxide superconductor has superconducting characteristics being uniform in its widthwise direction, and it can be manufactured at high speed.

An object of the present invention is to provide a medium; a specimen; a method for preparing the specimen; a method for observing the specimen; a sample cell; and an electron microscope capable of easily solving the problem of charge-up and further capable of observing a real shape or the like of a sample with a SEM, a TEM or the like. For the purpose of achieving the above-described object, the present invention uses an electrical conductivity-imparting liquid medium, for use in a microscope, which includes an ionic liquid as an essential component thereof and is impregnated into the entirety of a SEM or TEM sample or applied to the observation surface of a SEM or TEM sample to impart electrical conductivity at least to the observation surface of the sample. According to the present invention, the charge built up on the sample surface can be released simply by impregnating or coating the sample with the ionic liquid, and hence the problem of charge-up can be easily solved. Further, even when a sample impregnated or coated with the ionic liquid is placed under vacuum, the ionic liquid is not evaporated from the sample, and hence a biological sample can be observed as it is in an original shape.
