Everyone knows that perfumes are divided into top notes, middle notes and post notes, but I really want to come up with a perfume that allows you to distinguish the scent in it, which is probably not something that ordinary people can do. And some people are born with a good nose. They are particularly sensitive to various fragrances and can distinguish them one by one. Perfumer is such a person. Scientists are also looking for answers to why different people have different levels of sensitivity to the ELISA kit for fragrance.
Recently, Richard Newcomb of the New Zealand Institute of Plants and Foods and colleagues published two articles in the journal Current Biology, suggesting that genetic variation may play a role in the sensitivity of individuals to specific odors and the perception of those odors through smell and taste .
The sensitivity of odor can be inherited, and the related genetic variation is usually located near the olfactory receptor (OR) gene. In this ELISA kit study, Newcomb and colleagues selected 10 odors from fruits and dairy products, and then tested the subject's sensitivity to each odor. Using a whole-genome chip, the researchers discovered the genetic association of four odors. These variations are independent of each other, meaning that the sensitivity to one fragrance is not related to the sensitivity to another fragrance.
