Genetic Taste Test Strips, PTC, 12 x 100 Strips

PTC (pheylthiocarbamide) taste test paper test for the genetically controlled ability to taste this substance. Consisting of paper strips impregnated with a 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. 1.Remove a PTC taste test paper from the vial. 2.Stick out your tongue and place the strip on your tongue. 3.There are three basic results: bland, bitter, or vile. 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 and depends upon a homozygous dominant or heterozygous condition in the individual. PTC Taste Test Paper is perfectly safe to use. Any possible toxicity of PTC would be in grams per kilogram of body weight, which is millions of times greater than anything which would be found in these taste test strips. Phenylthiocarbamide (PTC) is present at only 20 micrograms per strip. At this level, the compound is negligible and harmless.
