Research Abstract

We planned to construct a novel taste sensor using the taste receptor protein. The taste censor should be present a stable score to the tastants. To measure the sweetness, we generated a cell line that were stably expressing the human sweet taste receptor (hT1R2/hT1R3). The cell could be worked as a sensor for sweet taste to obtain the change of fluorescent intensities of the intracellular calcium indicatordye.
