Technical Details

For decades, mice have been the major transgenic in vivo model for gene function studies and drug discovery. Their low maintenance cost and easy manipulation made them a preferred tool for pre-clinical research. However, there is still a significant void in animal models required for specific research purposes which the mouse models have been unable to fill. As the need for a better understanding of human genetics has grown, there has been an increased demand for improved transgenic animal models.

Rat models are making a comeback as a preferred in vivo model for researchers who seek a better representation of human genetics and physiology. The successful isolation of rat embryonic stem cells (rES) and complementary accomplishments in site-directed mutagenesis using techniques such as TARGATT™, CRISPR/Cas9, ZFNs and TALENs have made the generation of transgenic rat models possible. 

Why do we need transgenic rat models?

  • Mouse models are not always reliable in preclinical studies and have several limitations for modeling human diseases
  • The metabolism, physiology and pathology of rats are closer to human than mice
  • The larger size of rats allows for sophisticated surgeries, instrumentation and manipulations
  • Excellent behavioral models for cognition and memory, neurological and psychological assays and drug screening
  • Superior model for cardiovascular diseases (stroke and hypertension), autoimmune disorders, diabetes, breast cancer, and autoimmune disorders
