  • Publication number: 20240069033
    Abstract: A method for screening for a molecule capable of forming a complex with a plurality of target molecules has been found by applying an affinity-based method for recovering a candidate molecule to techniques represented by Split GFP techniques. The method includes allowing a first target molecule linked to a first moiety of a protein, a second target molecule linked to a second moiety of the protein, and a library containing a plurality of test molecules to coexist, and recovering a test molecule capable of forming a complex with the first target molecule linked to the first moiety and the second target molecule linked to the second moiety by an affinity technique.

  • Patent number: 8685914
    Abstract: The present invention provides: (1) crystals of a dipeptide which do not substantially comprise a dipeptide comprising D-amino acid as a constituent or a polypeptide consisting of three or more amino acids; and (2) crystals of a dipeptide which do not substantially comprise a dipeptide comprising D-amino acid as a constituent, a polypeptide consisting of three or more amino acids, or an amino acid amide; and a process for producing the dipeptide crystals.

  • Publication number: 20090306340
    Abstract: The present invention provides: a method for purifying an oligopeptide, which comprises a step of contacting a solution comprising the oligopeptide and a neutral amino acid with an ion exchange resin in an effective pH range; the method for purifying an oligopeptide, which comprises (a) a step of passing a solution comprising the oligopeptide and the neutral amino acid through a column packed with an ion exchange resin, and (b) a step of eluting the oligopeptide contacted with the ion exchange resin with an eluting solvent; the above method using a weakly acidic cation exchange resin; the above method using a weakly basic anion exchange resin, etc.

  • Publication number: 20030038075
    Abstract: A hollow fiber membrane module having a structure, in which raw water is supplied into a filtration chamber containing a hollow fiber membrane and surrounded by a first sealing body having the open ends of the numerous hollow fiber membranes constituting the hollow fiber membrane bundle, a cylindrical case and a second sealing means, through a raw water supply port formed in the cylindrical case at a position near the second sealing body, and in which the drain of backwashing is discharged through a drain port formed in the second sealing body.

  • Patent number: 5794777
    Abstract: A container for a web-shaped photosensitive material having a core on which is placed the web-shaped photosensitive material in the form of a roll, a port opening via which the web-shaped photosensitive material is taken out, and light-shielding plushes disposed at the port opening. The light-shielding plush is dyed with a colorant dye having spectral absorption (SQ value) in at least a region of spectral photosensitivity of a red-sensitive layer of the web-shaped photosensitive material. Light fog is prevented.
