“We are a highly flexible team and strive to be at the forefront of developments in the field, frequently expanding our In Vivo and bioanalytical capabilities to meet the demands of new studies,” says Julien Roeser, general manager.
Among its In Vivo offerings, Quantall provides all standard dosing routes for rodent studies, including intravenous (IV), intraperitoneal (IP), oral (PO) and subcutaneous (SC) administrations, as well as specialized routes such as intranasal (IN), intradermal (ID), intramuscular (IM) and hock injections. It also offers proficient stereotaxically-guided drug delivery, both acute and chronic, and has the surgical expertise to perform intracerebroventricular (ICV) & Intrathecal (IT) injections in order to deliver drugs directly into the brain.
A core and unique specialty at Quantall is to conduct microdialysis experiments. Quantall is equipped to implant microdialysis probes in specific brain regions to sample compounds directly from local areas, as well as in the jugular vein for systemic sampling of free circulating drug or endogenous biomarkers in freely moving subjects.
On the bioanalytical side, Quantall offers comprehensive quantitative services using liquid chromatography-mass spectrometry (LC-MS/MS) and immunoassay platforms. Highly versatile LC-MS/MS workflows allow Quantall to work with a wide variety of biological matrices and animal species. For immunoassays, it offers large molecule analysis using advanced platforms such as ELISA and MSD.
