Euglena cells by non-scanning absorption spectroscopy imaging" with Tokyo University of Science was published on April 12 in the English journal "Journal" of the Botanical Society of Japan. It was published in "of Plant Research".

Euglena may produce hematochrome-like granules containing a reddish-colored pigment in the cells, but its appearance and absorption spectrum ^* are very similar to the eye spots at the base of the flagella. In this study, we showed that they can be distinguished based on the hematochrome-like granules and the detailed absorption spectrum of the eye spot. * Wavelength pattern of light absorbed when light of continuous wavelength is transmitted through a substance
The results of this research are expected to be applied to new methods that can evaluate the pigment components of living Euglena
