Preclinical Assay Development and In Vivo Services

Custom In Vivo Models and Testing Solutions

Selecting the appropriate in vivo model for your assays is critical for the success of your preclinical research program. At Nexelis, a Q² Solutions Company, we designed and developed disease specific in vivo models alongside bespoke personalized model development services. Our wealth of experience and capabilities allows us to help answer our clients’ research questions and aid with the most appropriate study design. We provide non-regulated, preclinical development solutions that include performing experiments, analysis, reporting, and technical writing.

In addition, our preclinical service capabilities include custom designed and BSL-2 challenge in vivo models. Our scientists specialize in immunology, bacteriology, virology, physiology, and cell-based assays analysis. These platforms are utilized within our diverse portfolio of projects, including a range of assays to assess both humoral and cellular immunity.
