About us

High-Quality Drug Transporter Assays

Founded in 2009 in Göttingen, Germany, PortaCellTec Biosciences GmbH combines extensive experience with decades of scientific expertise in membrane transporters and their interactions with drugs.

We offer a comprehensive portfolio of drug transporter assays using cell systems with human transporters stably overexpressed in HEK293 (human embryonic kidney) cells.

Our assay systems are characterized and validated using specific probe substrates and reference inhibitors.

Our primary focus is on human drug transporters. At the same time, we are continuously expanding our portfolio to include transporters from preclinical species such as mice, rats, dogs and monkeys.

This enables us to support translational research and drug development from preclinical studies through to clinical development.

Whether you need individual transporter assays, comprehensive interaction studies or scientific guidance, our team is ready to support your research with tailored solutions and reliable data.

Contact our scientific team to discuss your requirements and find the right approach for your transporter studies.
