    摘要: PROBLEM TO BE SOLVED: To provide a useful antibody for measuring activity of von Willebrand factor (VWF) nicking enzyme (ADAMTS13), in particular, a monoclonal antibody and a method for measuring ADAMTS13 activity.SOLUTION: There are provided a monoclonal antibody which has specific reactivity to an antigenic determinant site having a specific amino acid sequence, but has no specific reactivity to the complete VWF molecule, produced by reacting ADAMTS13 with VWF that is a substrate or a partial peptide of VWF that is a potential substrate, and a method for measuring ADAMTS13 activity using the antibody.

    摘要: PROBLEM TO BE SOLVED: To provide a method for maintaining the reactivity of fine particles bonded with a reactive substance dispersion liquid for a long period of time by stabilizing the fine particles in the dispersion liquid of the fine particles bonded with a reactive substance. SOLUTION: The present invention provides a stabilization method for the fine particles bonded with a reactive substance, and the method includes a step of letting a sulfur-containing amino acid or a derivative thereof to coexist in the dispersion liquid of the fine particles. The preferable sulfur-containing amino acid includes cysteine, cystine and methionine. The method is particularly useful when a sedimentation suppressing substance such as a polyanion and dextran coexists in the dispersion liquid. COPYRIGHT: (C)2010,JPO&INPIT
