Marksman Cellject Inc is a spin-off from the Innovations Group of the University of Toronto.

Professor Yu Sun, Director of the Advanced Micro and Nanosystems Lab in the Department of Mechanical and Industrial Engineering, completed an NSERC I2I supported grant to develop an automated system for injection zebrafish embryos. Injectionwith ~100% success, survival, and phenotypic rates were ahcieved. The system and its performance were summarized in recent publications. The cell preparation and injection process can be seen in this video.

In collaboration with Dr. Robert Casper of the Samuel Linenfeld Research Institute, Mount Sinai Hospital, Toronto, Marksman Cellject Inc. is extending its patent-pending technology to provide automated cell injection solutions to mouse and human cells. This development is partly funded by a grant from the Ontario Centres of Excellence with generous equipment support by Nikon Canada.

Under the collaboration program, Dr. Casper's group will test and evaluate a demonstration prototype for applications in mouse and human IV (in vitro fertilization).

As different types of cells pose cell-specific preparation and injection requirements, Marksman Cellject would discuss specific requirements and provide custom injection machines to serve diverse application needs for automated, fast, accurate and reliable cell injection.
