Acting and reacting in life science biotechnologies
In a previous post, we introduced our Ready-to-use cellular models for SLC assays by GenoMembrane.
These cell lines transiently express the current FDA and EMA recommended SLC drug transporters (eg. OCT1 and OCT2; OAT1 and OAT3; MATE1; MAT2K…). Conditioned as cryopreserved format, they provide flexibility for experimental planning and can be assayed in just 2 days.
Human and Animal Dermal S9 Fractions now available as standard products
Subcellular fractions are widely used in drug discovery and preclinical drug development to evaluate the in vitro metabolism of new therapeutics. Skin fractions are already available from tebu-bio as catalogue items for CD1 Mouse and IGS Sprague Dawley Rat.
In collaboration with Sekisui XenoTech, tebu-bio is now adding human and minipig dermal subcellular fractions to the list of species available as standard test systems. [Read more…]
A wide range of in vitro models are used in preclinical drug testing for the investigation of ADME-Tox (Absorption, Distribution, Metabolism, Excretion and oxicity) properties of New Chemical Entities (NCEs). The liver is the main organ with regards to ADME-Tox, it’s the place of more than 500 different functions, including: metabolism of lipids, carbohydrates, and vitamins, detoxification, production of bile, albumin, fibrinogen, globulin, etc (1). The liver lobule is composed of parenchymal cells (hepatocytes) and nonparenchymal cells (Kupffer cells, hepatic stellate cells, and sinusoidal endothelial cells).
Hepatocytes represent 80% of liver volume. Hepatocytes are commonly used in drug discovery and preclinical drug development to perform experiments requiring intact cellular systems. Intact hepatocytes contain the major hepatic drug-metabolizing enzymes required to study the four categories of xenobiotic biotransformation: hydrolysis, reduction, oxidation and conjugation.
Because of these enzymes, hepatocytes provide a viable and cost-effective alternative to in vivo testing. [Read more…]
