Knockout Rat Models
Since 1998, ingenious targeting laboratory has completed over 2,800 generated gene targeting projects across multiple species, including rat, enabling loss of function studies in larger rodents offering superior behavioral characterization and physiological readout capacity.
Knockout rat models provide distinct advantages for studies examining behavioral responses, cardiovascular physiology, renal function, and complex neurobiological phenomena where rodent size or documented behavioral capacity offers superior scientific value compared to mouse models. The trade off between increased project timeline and cost against superior phenotypic readouts makes knockout rats optimal for specific research questions despite greater complexity.
Frequently asked questions
Yes, multiple mutations in several genes are feasible in rats, though knockout efficiency typically decreases with increased target number.
Morris water maze, open field tests, elevated plus maze, and novel object recognition effectively characterize behavioral phenotypes in knockout rats. More complex learning paradigms including 5 choice serial reaction time and operant conditioning reveal subtle cognitive changes invisible in simpler behavioral assays.
Yes, rat body size and commercial telemetry system availability make cardiovascular telemetry studies highly practical. Implanted transmitters enable continuous blood pressure, heart rate, and ECG monitoring throughout lifespan, revealing phenotypes impossible to detect in mice.
