    摘要： In a surface plasmon resonance sensor including a chip with a substrate 102 and a metal layer 103, a prism 104, an optical system 105 serving as a light source, and a light detector 106, the metal layer 103 is configured by a flat part 109 formed into a thin film, and convex parts formed from metal particles 110 and the like arranged spaced apart from each other. When light enters the metal layer 103 of such configuration, resonance angle arising from the flat part 109 and the convex parts are respectively obtained. The change in index of refraction of a medium contacted by the metal layer is detected from such resonance angle.

    摘要： A simple and low-cost method of selectively modifying the C-terminal of a protein or peptide is provided. A method of modifying the C-terminal of a protein or peptide comprises forming an intramolecular oxazolone ring at the C-terminal of the protein or peptide that requires C-terminal modification, and then performing a ring-opening of the oxazolone ring to produce a protein or peptide with a modified C-terminal. Preferred forms include a method in which by reacting the oxazolone ring with a compound containing a nucleophilic group to effect an oxazolone ring-opening, a protein or peptide is produced in which the C-terminal is modified with the compound containing the nucleophilic group, as well as a method in which by reacting the oxazolone ring with an active esterifying agent to effect a ring-opening, the oxazolone is converted to an active ester, which by subsequent reaction with a compound containing a nucleophilic group, produces a protein or peptide in which the C-terminal has been modified with the compound containing the nucleophilic group.

    摘要： The present invention provides a method for selectively collecting the N-terminal peptide fragments of a protein of interest whether or not the protein of interest is modified on the N-terminus. A method for selectively collecting the N-terminal peptide fragment of a protein, comprising: a protection step (1) of protecting side chain-amino groups of amino acid residues containing side chain-amino groups of a protein of interest to obtain a protected protein protected on the side chain-amino groups; a fragmentation step (2) of cleaving the protected protein into one N-terminal peptide fragment (a) containing the N-terminus of the peptide of interest and one or more of peptide fragments (b) other than the N-terminal peptide fragment (a); and a separation step (3) of separating the N-terminal peptide fragment (a) from the other peptide fragments (b) by selectively eluting the N-terminal peptide fragment (a) based on the difference in their reactivity or affinity to substrate, wherein the selective elution is achieved either by allowing the other peptide fragments (b) to bind to the substrate while allowing the N-terminal peptide fragment (a) to elute, or by allowing the N-terminal peptide fragment (a) to bind to the substrate while allowing the other peptide fragments (b) to elute and subsequently eluting the bound N-terminal peptide fragment (a).
