Challenge multiple muscle systems in your mice by having them pull a weightedsled while walking or running. As in human life, problems with strength and mobility may not occur until muscles, bones, and joints are challenged. The sled kit empowers the researcher to have the animals pull up to ~300% of their body weight to identify early and subtle phenotypes. The “harness” is a natural paper sleeve, that adheres via an herbal glue for temporary hold on the base of the subject’s tail [the mice will usually remove the harness after several hours, and consider it cage enrichment!]. Kit includes sled, weight set, and 10 disposable harnesses.
