Phenylthiourea PTC Genetic Taste Test Strip, 5-Vial Case

This pack contains 5 vials of phenylthiourea (PTC) test strips, with 100 strips per vial. Each strip measures 6mm x 48mm and contains 30 micrograms of PTC, a safe quantity for taste testing. PTC is a chemical compound that approximately 7 out of 10 people can taste, while the remaining 3 cannot. When placed on the tongue, the PTC-coated strip dissolves and releases the compound, which interacts with taste receptors. Individuals who can taste PTC will experience a bitter or unpleasant sensation, while non-tasters will detect no particular flavor. These strips are commonly used in educational settings to demonstrate genetics, heredity, and the genetic basis of taste perception. The clear storage vials keep strips dry and accessible for repeated classroom use.
