They screened these by assuming that a taste receptor would only be found in a small number of tissue types (specifically tongue taste cells). That whittled the list down to 900.

他们通过假设味觉受体应该只在很少种类的组织(特别是舌味觉细胞)中被发现，把名单缩减到900个。

Teixeria has already determined that the sweetness of thaumatin is related to the specific charges across a large surface area over which thaumatin can bind to the principle human taste receptor.

特谢拉已经确定这种甜蛋白的甜度与蛋白表面某一区域的特定电荷有关，这一区域同人们主要的味觉受体相结合。

Swabs were also taken of the volunteers' cheek cells so that researchers could determine whether they carried none, one, or two 'sensitive' copies of the taste receptor gene that allows taste of PTC.

研究者再用棉签刮取志愿者口腔的细胞，这样他们就能确定志愿者是否含有或者是否含有多个争对PTC的“敏感型”受体基因。

For example, a recent study by researchers at the University of Pennsylvania and the Monell Center showed that supertasters were better able to fend off bacterial sinus infections because of a particular bitter-taste receptor in their nose.

Dr Munger, though, found that both GLP-1 and the receptor molecule that picks it up and thus allows it to act are found in taste buds too.
