  • Publication number: 20220119498
    Abstract: To provide an immunoglobulin purification method which achieves a high immunoglobulin recovery percentage without causing loss of the antibody nature of an immunoglobulin. The immunoglobulin purification method includes an adsorption step and a desorption step. The adsorption step involves adsorption of an immunoglobulin onto porous zirconia particles in a neutral buffer. The desorption step involves desorption of the immunoglobulin adsorbed on the porous zirconia particles from the porous zirconia particles by means of a neutral desorption liquid.

  • Publication number: 20220089453
    Abstract: Porous zirconia particles exhibit high specificity to a protein to be immobilized thereto and are used in immobilization of the protein. The porous zirconia particles have a pore diameter D50, at which a ratio of a cumulative pore volume to a total pore volume is 50%, the pore diameter D50 being in a range of 3.20 nm or more and 6.50 nm or less; and a pore diameter D90, at which a ratio of a cumulative pore volume to a total pore volume is 90%, the pore diameter D90 being in a range of 10.50 nm or more and 100.00 nm or less. The total pore volume of the particles is greater than 0.10 cm3/g. D50, D90, and the total pore volume are determined based on a pore diameter distribution measured through a BET method.

  • Publication number: 20210397662
    Abstract: By showing information that can infer the search intent, it will be possible to develop products and create Web pages that match the search intent. A search needs evaluation apparatus acquires a plurality of document data and converts the contents or the structure of the plurality of document data into feature vector data. The search needs evaluation apparatus performs a process on the feature vector data according to a predetermined statistical identification algorithm, and classifies a plurality of document data into a plurality of subsets. The search needs evaluation apparatus outputs the analysis result of the property of search needs based on the relationship between a plurality of subsets.
