Invivotek

All Assays for Phenotyping


The Invivotek’s phenotyping program offers over 90 bioassays for evaluating effects of genetic modifications on physiology and behavior of mice. Our unique expertise in multiplexing bioassays spanning multiple therapeutic areas, allows us to perform multiple assays on a group of animals, maximizing the data set per animal without compromising its integrity. Multiplexing provides a powerful industrial tool for a liability assessment of potential on-target side effects and early identification of new therapeutic indications for genetic targets.
