[December 1, 2023] New publication: Ando et al., Nat Methods

Miyawaki group in RIKEN, in collaboration with the member of ZEISS-iCeMS Innovation Core, developed monomeric StayGold and improved tandem dimer variants. Momomeric StayGold gained higher resistance to strong excitation light and faster maturation than original StayGold. Volumetric imaging of cristae membrane dynamics in a cell-wide manner was performed by Lattice SIM^2 (below: acquisition by Dr. Anna Löschberger and movie processing by Dr. Kirstin Elgass of Carl Zeiss).

[March 28, 2022] Online Seminar (via Zoom): Towards fast and gentle super-resolution microscopy

Super-resolution fluorescence microscopy is rapidly evolving the field of biomedical research. Recent technical developments are mainly focused on fast and gentle observation of dynamic cellular structures ranging from mesoscale (20~500 nm) molecular assemblies to highly organized cell organelles.

In this online seminar, first, the scientific lecture on the development of novel fluorescent proteins to improve observations of various cellular processes is given by Dr. Atsushi Miyawaki (RIKEN CBS). Next, the technical lecture on the features of two ZEISS super-resolution microscopes “Elyra 7 with Lattice SIM2” and “LSM 980 with Airyscan 2”, available at ZEISS-iCeMS Innovation Core, is given by Dr. Klaus Weisshart (ZEISS Jena, Germany).

Elyra 7 was just installed as shared equipment of MaCBES (Main Campus Base of Equipment Support), Kyoto University in December 2021. After the seminar, we will have onsite demonstration sessions for Elyra 7 using your samples (about 2 hrs each) on March 29, 30, and 31.

[April 7, 2020] iCeMS Specially Appointed Professor Fumiyoshi Ishidate, member of ZEISS-iCeMS Innovation Core, was selected to receive the "Outstanding Support for Research Award" of the "Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology" for 2020.

The "Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology (科学技術分野の文部科学大臣表彰)" honors those who have made remarkable achievements in the field of science and technology, and the "Outstanding Support for Research Award (研究支援賞)" is a newly established award given to those who supported the progress of research and development activities though their highly professional knowledge and skills. Prof. Ishidate is one of the first winners of this honorable award.

Prof. Ishidate has made great contributions to iCeMS imaging facility for these 10 years, especially as a mentor of live cell imaging using ZEISS microscopes. He provided one-on-one training sessions to a cumulative total of 600 researchers inside and outside the university. In addition, through the collaboration with iCeMS Kageyama group, he developed the "long-term microscopic observation technique for weak signals in living cells" taking advantage of his deep knowledge of live cell samples and skills to operate advanced confocal microscopes. Using the developed technique, time-lapsed imaging of weak signals from the fate-determination transcription factors in neural progenitor cells was successfully performed for the first time. It resulted in the finding that the multipotent state correlates with oscillatory expression of several fate-determination factors, whereas the differentiated state correlates with sustained expression of a single factor (Imayoshi et al., 2013, 2015), which attracted worldwide attention.

Prof. Ishidate also made continued efforts to establish the long-standing partnership between iCeMS and ZEISS German headquarters, and based on the partnership, we were able to launch the ZEISS-iCeMS Innovation Core in 2019.

Congratulations, Ishidate-san!

[January 27-29, 2020] ZEISS Elyra 7 with Lattice SIM Workshop

A workshop for Elyra 7 with Lattice SIM, newly developed lattice structured illumination-based super-resolution microscope system, took place at ZEISS-iCeMS Innovation Core on January 27-29.

In Lattice SIM, the sample area is illuminated with a lattice pattern instead of grid lines. The lattice pattern gives higher contrast and 2x higher sampling efficiency compared with conventional SIM, so that you need less illumination. This is a breakthrough in light efficiency, enabling fast live imaging of 3D volumes at excellent resolutions (120 nm in XY and 300 nm in Z) while minimizing photodamage.

Dr. Bernhard Zimmermann (Senior Director Business Sector Life Sciences, ZEISS Research Microscopy Solutions, Jena, Germany) gave a seminar on Lattice SIM technology and its comparison to other super-resolution methods. After the seminar, demonstration sessions using own samples (about 2 hrs each) were arranged.
