PRIMACYT provides subcellular liver fractions from human and a variety of animals for use in drug development in human and animal health. Also, liver cells and subcellular liver fractions are provided for environmental toxicology studies of herbicide and pesticide metabolism and bioaccumulation studies in birds and fish, like rainbow trout (Oncorhynchus mykiss) or Atlantic salmon (Salmo salar). S9 fractions and microsomes from species not listed above, e.g., turkey (Meleagris gallopavo), Mallard duck (Anas platyrhynchos) or Japanese quail (Coturnix japonica) can be made available upon request. Please ask.
The Liver microsome, S9 fractions, and cytosolic extracts are characterized by SDS-PAGE analysis and the determination of Cytochrome P450 activities. In subcellular fractions derived from human donors, we monitor the specific activities of cytochrome P450 and UDP-glucuronosyl-transferases (UGT).
