The present invention provides a method of enhancing an enzymatic activity of ADAMTS-13 and/or a method of reducing reactivity to an anti-ADAMTS-13 neutralizing antibody as well as a mutant of ADAMTS-13 prepared by the methods. The method of the present invention is characterized by substituting at least one charged amino acid in a disintegrin-like domain, a cysteine-rich domain or a spacer domain of ADAMTS-13 other than the following amino acids with a different amino acid: arginine at position 326, aspartic acid at position 330, aspartic acid at position 343 and arginine at position 349 in the disintegrin-like domain, aspartic acid at position 480, arginine at position 488, arginine at position 498, arginine at position 507, aspartic acid at position 533 and aspartic acid at position 543 in the cysteine-rich domain, and glutamic acid at position 641 and arginine at position 660 in the spacer domain. The present invention also provides a therapeutic agent for thrombotic disease comprising as an active ingredient the mutant of ADAMTS-13 prepared by the method.
摘要:
The present invention provides for a method for improving properties of an antibody such as an expression level and stability. A method for obtaining an antibody with an improved expression level and/or stability by modifying a human antibody or a humanized antibody, characterized by that at least any one of the amino acid residues at position 8, 12, 15 or 18 (according to Kabat numbering) in a light chain variable region (hereinafter referred to as "VL chain") of a human antibody or a humanized antibody is substituted with a different amino acid other than proline or cysteine, and a human antibody or a humanized antibody or a human antibody fragment or a humanized antibody fragment with an improved expression level and/or stability which are obtained by said method.
摘要:
Means for producing an MgB2 single crystal and a useful superconductive material using the anisotropic superconductive characteristics thereof. A mixture material of Mg and B or a precursor containing MgB2 microcrystals produced by reacting them is brought into contact with hexagonal crystal BN, and they are held at high temperature (1300 ° C to 1700 ° C) under high pressure (3 to 6 GPa) so as to grow anisotropic MgB2 single crystals having superconductive properties through intermediate products. The single crystal has a feature that the irreversible magnetic field is 95% or more of the second critical magnetic field depending on the direction of the applied magnetic field, and therefore can be a superconductive material having excellent characteristics by adjusting the crystal orientation. It is advantageous for single crystal growth to be coexistent with a reducer such as Mg during the reaction or by establishing a temperature gradient in the melt.
