Microbix Announces Proof-of-Concept Demonstration for LumiSort™ — its Livestock Semen Sexing Technology

Flow Cell Could Take Cytometric Semen Sexing To a New Level of Speed and Accuracy

TORONTO, May 4 /CNW/ - Microbix Biosystems Inc. (TSX:MBX), a biotechnology company commercializing novel technologies for livestock semen sexing and other innovative biologics, announced today that it has achieved a major development step for LumiSort™, its semen sexing technology.

Microbix reports that LumiSort has now achieved early "proof-of-concept" for the key component of this cutting-edge technology. Further, the developmental analysis completed by Lathrop Engineering Inc., a leading Silicon Valley technology development company, has demonstrated that Microbix' technology may enable the analysis and separation of sperm cells up to 10 times faster, and with higher precision compared to current market technology . The technology is useful for all kinds of cells, including asymmetric, non-spherical cells like sperm that are difficult to analyze on conventional cytometers.

Supporting these results, Microbix has again broadened its aggressive intellectual property strategy to cover LumiSort's applications. The company is also reaffirming its product pipeline guidance and expects to launch LumiSort in the second half of 2012.

William J. Gastle, Microbix' Chief Executive Officer said, "With today's proof-of-concept achievement and its demonstration of potential breakthrough cytometric attributes, LumiSort's upside could transform Microbix into a major technology development company with significant licensing revenues."

Robert Lathrop, founder and CEO of Lathrop Engineering, said, "We are pleased to join with Microbix in the development and engineering of their novel technology for sperm cell sorting and the general cytometry market. In our work to realize the concepts described in the intellectual property underlying the LumiSort device, we have been impressed by the simplicity and power of the approach. LumiSort addresses the historically difficult problem of sperm cell sorting in a new and innovative way, and we expect this discovery to result in significant gains in throughput and efficiency."

Microbix has established agreements for LumiSort with companies located in the United States, Canada, Australia, Europe, South America, and China representing more than 35% of the dairy semen collection centers and will enter a global animal reproduction market for artificial insemination valued at more than $ 3 billion. All agreements include the same royalty payment to Microbix of 15% of selling price. Now, within 18 months of launch, the Company is accelerating its program to sign license agreements with additional distributors.

In 2010, Microbix announced two partnerships including one with an engineering firm focused on the development of the technology and the other with one of the largest suppliers of livestock reproduction products in the world. The second firm has invested in the program through a milestone based, $2 million investment, and will rapidly deploy LumiSort into their markets.

About Microbix' LumiSort™

LumiSort is a completely new concept in instrument based selection technology that will improve the yield and quality of sexed semen by a significant margin over methods used in the livestock industry today. It incorporates a novel and innovative instrument design to address fundamental problems with existing commercial sex selection technologies, while providing Microbix with a strong and well differentiated intellectual property advantage in the industry. Microbix expects to introduce LumiSort to the dairy and beef livestock management markets before the end of 2012. The technology will not only provide a much higher quality product leading to higher conception rates, but is also expected to improve significantly the sexed semen production yield.
