  • Protein aggregation inhibitor
    Patent number: 10995160
    Abstract: The present invention provides a protein aggregation inhibitor for use in preventing aggregation of a protein, which contains a terminal sulfanyl group-containing sulfobetaine polymer having a repeat unit derived from a sulfobetaine monomer represented by the formula (II), and a noble metal particle, and in which the terminal sulfanyl group-containing sulfobetaine polymer is chemisorbed on the noble metal particle by the sulfanyl group (the groups in the following formula are as defined in the DESCRIPTION).

  • PROTEIN AGGREGATION INHIBITOR
    Publication number: 20180118859
    Abstract: Provided is a protein aggregation inhibitor capable of inhibiting aggregation of a protein even when the protein is heated, and further, capable of inhibiting a decrease in the protein activity even when the protein is heated, which characteristically contains a sulfobetaine polymer obtained by polymerizing monomer components containing sulfobetaine monomer represented by the formula (I): wherein R1 is a hydrogen atom or a methyl group, R2 is an alkylene group having a carbon number of 1-4, R3 is an alkyl group having a carbon number of 1-4, R4 is an alkylene group having a carbon number of 1-4, and X is an —NH— group or an —O— group.
