  • Publication number: 20200262873
    Abstract: Provided are a protein L-derived immunoglobulin binding protein having an increased antibody dissociation rate under acidic conditions, and an affinity support using the same. Disclosed are an immunoglobulin binding protein comprising at least one mutant of an immunoglobulin binding domain, and an affinity support comprising a solid-phase support having the immunoglobulin binding protein bound thereto. A mutant of the immunoglobulin binding domain consists of an amino acid sequence having an identity of at least 85% with the sequence set forth in any one of SEQ ID NO:1 to SEQ ID NO:9 and a predetermined mutation, and the mutant has immunoglobulin ? chain binding activity.

  • Publication number: 20200150113
    Abstract: To provide a novel technique with which the generation of aggregates over time in a dispersion liquid can be suppressed and a target substance can be detected with high sensitivity even if latex particles that have been stored are used. A method for storing in a container a latex particle dispersion liquid in which latex particles for an extracorporeal diagnostic agent are dispersed, the latex particles having a volume average particle size of 10 to 1000 nm and including a polymer containing 70 to 100% by mass of monomer units each derived from a monomer having an aryl group relative to the total monomer units, which is characterized in that the particle dispersion liquid is stored in the container by setting a ratio of a volume of a void space obtained by excluding a volume occupied by the particle dispersion liquid from an internal volume of the container to 0 to 25% (v/v) relative to the internal volume of the container.

  • Publication number: 20180284109
    Abstract: This invention relates to a method of producing a probe-bound carrier, a probe-bound carrier and a method of detecting or separating a target substance. The method of producing a probe-bound carrier includes: step 1 of mixing a carrier having tosyl groups and a probe; and step 2 of reducing the amount of tosyl groups on a surface of a carrier, in which a proportion of area S2 that is occupied by one tosyl group on a surface of the carrier obtained in the step 2 with respect to area S1A that is occupied by one tosyl group on a surface of the carrier used in the step 1 (S2/S1A×100%) is not less than 140%.

  • Publication number: 20040229453
    Abstract: One method includes porous low k pore sealing that uses a combination of materials that bond and expand, thereby covering any pore or irregularities in the surface of an insulator adjacent to a conductor. The materials form a substantially impermeable barrier between the conductor and insulator that prevents leakage of the conductor into the insulator. Another method encapsulates the conductor on all exposed surfaces with an impermeable barrier before placement of an insulator, thereby preventing both anode extrusion and diffusion via pores in the insulator.
