Product Details

Popular in the study of human genetics, Mendelian genetics and family pedigrees. Tests are harmless and easy to interpret. All are supplied in vials of one hundred 2" × ¼" strips.
Specifications
*PTC paper is paper soaked with phenylthiocrabamide (PTC). The LD50 for PTC is 3 mg/kg. Such a low LD50 suggests that this is a very toxic substance. The solution to make the taste test paper contains approximately 50 mg of PTC per liter of water. We calculate that each strip of PTC would contain approximately 0.03 mg of PTC. We estimate that a person weighing about 50 kg (110 pounds) would have to lick and ingest 5,000 2" × ¼" strips of PTC paper to reach the LD50. A few sensitized individuals may have an allergic reaction to PTC.
