Genetic test kit for PTC sensitivity

Objectives:
Highlight that taste perception related to the presence of a molecule, PTC (Phenylthiocarbamide), varies from one individual to another, ranging from a strong perception of bitterness to no perception.
Connect this observation to the notion of genetic diversity within a population.

Explanation:
The TAS2R38 gene codes for a taste bud receptor.
Individuals who possess the mutated version of the gene will be sensitive to the PTC molecule.
Individuals with the non-mutated version of the gene will not be sensitive to bitterness.

Implementation:
Students apply the (single-use) strips on their tongue and describe their sensation.
Sensitivity to PTC depends on a gene mutation. This phenotype can be confirmed by genotype analysis through PCR.

Format: 100 complete tests
Duration of the experiment: 10 min
Shelf life: 24 months
Storage conditions: Room temperature, dry 

The kit consists of:
- 1 pack of 100 PTC test strips
- 1 pack of 100 control test strips
