  • Vitamin D measurement method and measurement kit
    Patent number: 10571479
    Abstract: The present invention provides a method of measuring a vitamin D. Specifically, the present invention provides a method of measuring a vitamin D, comprising: (1) treating a sample with a surfactant having a steroid skeleton; and (2) detecting the vitamin D in the treated sample. The present invention also provides a kit for measuring a vitamin D, comprising: (1) a surfactant having a steroid skeleton; and (2) an affinity substance for a vitamin D and/or a vitamin D standard. Examples of the surfactant having the steroid skeleton may include a bile acid or a derivative thereof or a salt thereof.

  • Antibody against affinity complex
    Patent number: 9599608
    Abstract: The present invention provides a means and a method for specifically measuring a substance such as a small substance with high sensitivity by a sandwich method. Specifically, the present invention provides an antibody capable of specifically binding to an affinity complex and a method of measuring of the affinity complex comprising measuring the affinity complex using the antibody capable of specifically binding to the affinity complex. The antibody of the present invention may be a full-length antibody. The antibody of the present invention may also have a region derived from an immunoglobulin from an animal having an ability of gene conversion (e.g., a complementarity-determining region, a framework region, or a variable region). Examples of at least one factor that constitutes the affinity complex include a small substance or a protein (e.g., antibody).
