What's New

  • March, 2022
  • March, 2022
    • New transgenic lines and plasmid vectors have been added in our project. We are waiting for your request.
    • Transgenic lines labeling gnrh neurons with Kaede.
    • Transgenic line labeling Vasopressin neurons with Venus.
    • Genome editing constructs for mutating GABA related genes.
    • Genome editing constructs for mutating a gene encoding enzyme necessary for peptide hormone maturation.
    • Genome editing constructs for mutating gnrh and vasopressin genes.
  • January 2022
    • Functions of POUIV transcription factor for specifying epidermal sensory neurons have been revealed. In this report, NBRP transgenic lines expressing Kaede in the mature neurons were used. Click here for details.
  • October 2021
    • Our plasmid vector for genome editing was used for analyzing gene functions in Starfish. Our resources are always open for the use in organisms other than Ciona. Click here for details.
  • July 2021
    • The method culturing Ciona in a small aquarium was added on Protocol page.
