HCMS100 – Noninvasive tracking system to monitor group activity of lab animals

Image Viewer
​
  • Monitoring lab animals' activity and welfare is a crucial step in the process of drug discovery or vaccine research. To avoid subjective observation and to minimize animal interference, IIBR developed HCMS100 - a computerized hands-off home-cage monitoring system.
  • This system is based on a standard cage rack equipped with a single laser beam and a detector mounted on the cage rack, which enables to monitor and analyse animals' activity based on laser beam interruptions.
  • IIBR performed various experiments using the HCMS100 which include both mice and hamsters and rats subjected to different kind of challenges such as: bacteria, viruses (influenza* and SARS-CoV-2**) and toxins.
  • These experiments presented the differences between the control and experimental groups and verified that the monitored animal movement data correlates to the animal health status.
  • LSRI has filed patent applications for this technology, both in the US and in Israel.
  • LSRI intends to license the patent and its rights to use to international company for completion of the development, production and marketing of the technology.
