Biological sample: The YING-B2 experiment investigates one of the most intensively studied eukaryotic model organisms in molecular biology: the yeast Saccharomyces cerevisiae.

YING-B2 experiment: Yeast growth in different solid media is required by the scientists to find out the effects of microgravity on yeast colony organisation. At molecular level Flo proteins expression and functionality were analyzed.

Hardware performance: The EU is designed to allow yeast growth on different solid media, and yeast fixation. Each injection system can be activated apart from others, consequently
yeast cells fixation can occur at different timing. Moreover, the EU is provided with four CC so that each experiment is validated with the so called control experiment. Gas homeostasis is also maintained. These features make the hardware suitable to different experiment conditions and biological samples.
