Abstract
The invention relates to a method for determining whether a test compound can counteract malodour from a sulphur odorant. The method includes contacting the test compound and the sulphur odorant with an olfactory receptor OR4E2, and comparing the binding of the OR4E2 to the sulphur odorant, or the activity of the OR4E2, in the presence and in the absence of the test compound.
