In Vivo Efficacy Testing Services

“Aragen Biosciences is a versatile contract research lab that keeps expanding their services. Most recently, they have been a solid performer for my company’s animal studies…The Aragen team is very good at communicating and they consistently deliver quality results Thank you Aragen!” – Elisabeth Gardiner, PhD, Chief Scientific Officer, Meditope Biosciences, Inc

Our highly experienced team will guide you through in vivo testing by recommending the most appropriate animal models, conducting studies with well established protocols and generating reports customized to your needs. We have established a broad range of working animal models that support multiple therapeutic/disease areas.

Animal Models of Disease

In Vivo Expertise and Resources that Drives Outcomes

Our team will help you investigate different animal protocols and optimize planning and experimental design to ensure you get the most out of your in vivo studies. Because of our scale, we can quickly allocate the appropriate space and technical staff to carry out the designed experiments. We provide specialized platforms and technical expertise including ex vivo/in vitro testing and histological preparations. We also undertake non-GLP pharmacokinetic (PK), pharmacodynamics (PD), and toxicology screens.

Our campus includes a state of the art 15,500 square foot facility dedicated to in vivo pharmacology and ex vivo analysis and an additional 16,000 square foot facility for in vitro analysis. These resources, combined with our specialized expertise in animal handling, colony management and small animal procedures, help ensure a successful outcome to your pre-clinical studies.

Technology Focus: IVIS Imaging

One of the most powerful technologies available to assess tumor growth and development, as well as efficacy of candidate therapeutics, is Bioluminescence Imaging. We offer this powerful modality using PerkinElmer’s IVIS® Lumina XRMS system, which includes X-Ray and fluorescence imaging capabilities with precise overlay.

Application Example: IVIS Imaging and Caliper Measurement of Subcutaneous SK-OV-3-Luc Xenograft in Athymic Nude Mice

G2 Trastuzmab efficacy testing animal models

2 x 106 SK-OV-3-Luc cells were injected subcutaneously (SC) into the dorsal flank of female athymic nude mice.

Tumor growth was monitored for luciferase expression using the PerkinElmer IVIS at various time points. Mice were imaged 10 minutes post SC injection of luciferin at 150 mg/kg at various time points. IVIS imaging detected as early as Day 10 Post Injection (pi) of tumor growth compared to the caliper measurement.

IVIS is one of the many technology platforms that we employ.

The In Vivo Efficacy services performed by Aragen Bioscience are non-GLP studies performed exclusively in rodent models.

Aragen Bioscience has a long tradition of humane and proper use of laboratory research animals for biological and biomedical research. The Institutional Animal Care and Use Committee (IACUC) serves as an independent oversight committee responsible for monitoring all associated animal care and use at Aragen Bioscience.

The presence of IACUC and their responsibility in assuring adherence to federal, state, and institutional guidelines for all animal care and use are monitored by accrediting agencies that include USDA and the Public Health Service/National Institutes of Health/Office of Lab Animal Welfare (OLAW).

Additionally, Aragen Bioscience is fully accredited by the Association for Assessment and Accreditation of Laboratory Animal Care  (AAALAC). 

Aragen Bioscience also holds a Controlled Substance License from the U.S Department of Justice/Drug Enforcement Administration (DEA).
