Your Tool for Drug Discovery and Drug Development.


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.

    Overview
    Animals like Atlantic Salmon have been used in vivo by researchers for decades to assess bioaccumulation, metabolism, and environmental risk of chemicals, including drugs, xenobiotics, cosmetics, fragrances, flavoring substances, herbicides and crop protection products. Apart from Zebrafish, Rainbow trout is the best-studied fish species.

    The OECD Test Guideline 319B Determination of in vitro intrinsic clearance using rainbow trout liver subcellular fraction (RT-S9) was released on June 25, 2018. Primacyt now offers cryopreserved pools of rainbow trout S9 fractions prepared and characterized in accordance with this guideline.

    Further Application Fields

    Subcellular fractions are suitable for a variety of experiments including

    - Cytochrome P450 Inhibition Studies
    - Metabolite Characterization
    - Metabolic Stability
    - Cytochrome P450 Phenotyping

    Subcellular fractions derived from liver contain a rich variety of metabolic enzymes for assessing the in vitro metabolism of drug candidates and xenobiotics. They are used to evaluate active pharmaceutical ingredients in human and animal health. Other applications include the environmental toxicological assessment of agrochemicals and the evaluation of cosmetics and food additives.

    Our Competencies
    Your Primacyt Experts in Biology pertaining to the Liver

    PRIMACYT is approved by the European Commission as an EU Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) and serves as member of the laboratory network responsible for the method validation.

    Our colleagues are professionals and undergo continuous training in the preparation, isolation and cryopreservation of hepatocytes in general, including related co-products, methods and tools. We are a GLP certified laboratory since 2006.
    Rainbow Trout - a new in-vitro System
    More recently, researchers of the US Environmental Protection Agency (EPA), DuPont Haskell, the University of Bern and Fraunhofer IME have introduced trout hepatocytes as a reliable in-vitro system for bioaccumulation and clearances studies.

    Measurements of biotransformation rates in primary fish hepatocytes can be scaled up to the whole animal and thereby can provide data used in computational models to predict chemical bio-concentration factors in animals (K.A. Faye et al. 2014, I. Bischof et al. 2016).

    These and other supporting research results lead to the implementation of OECD Test Guidelines 319A and 319B on the determination of intrinsic clearance using cryopreserved rainbow trout hepatocytes and liver S9 subcellular fractions.
