PTC Paper Taste Test Strips for Genetics Labs
SKU: 33814-PTC
Teach Mendelian genetics with Indigo® PTC taste test strips. Explore TAS2R38 bitter receptor polymorphisms, taster vs. non-taster inheritance, and Hardy-Weinberg class experiments.
Indigo® PTC Taste Test Strips are the classic tool for demonstrating bitter taste genetics through the TAS2R38 receptor. Because PTC sensitivity is controlled largely by a single gene with well-defined PAV/AVI polymorphisms, it remains the most reliable classroom model of Mendelian inheritance, genetic penetrance, and population variation. These strips allow students to identify whether they are strong tasters, medium tasters, or non-tasters and compare class results to the Hardy-Weinberg distribution.
Use Indigo® PTC paper test strips in lab studies of inheritance of taste genotypes, only $3.25 per 100 strips. Compare the chemical structures of PTC (also known as phenylthiourea or phenylthiocarbamide) to that of the simpler thiourea. The phenyl ring in PTC may account for the wider range of taste responses.
PTC strips are used in biology lab experiments to help explain Mendelian Polymorphism and Genetic Penetrance. Document your results to compare where you fall in the Hardy Weinberg distribution.
