Genetic Taste Test Strips. Thiourea. 100 Strips. Our range of taste strips offers tests for genetically linked taste test ability. Consisting of paper strips impregnated with harmless quantity of test substance (or untreated in the case of the control strips), subjects will be able to detect (or not) varying tastes or degrees of intensity of taste. The ability to taste these substances is known to be genetically linked (inherited) and depends on the presence of dominant or recessive genes. Having the ability to taste one substance does not necessarily imply that different substance will also be detected. PTC (phenylthiocarbamide) test strips have bitter taste for some individuals, the intensity of which can vary. Thiourea test strips also have bitter taste sensation for some people. Sodium benzoate test strips have taste which varies from person to person and can be perceived as sweet, salty, sour or bitter (or, in some cases, no taste at all). Control test strips are untreated paper strips, used to provide negative response for comparison to the taste test strips.
