Labcyte Granted Patent for Acoustic Transfer of Living Cells and Solid Particles

Labcyte Inc. announced today that it has been granted its 16th patent, US 6,849,423, for the rapid and gentle transfer of cells and particles, including beads, with acoustic energy. This patent describes the use of focused acoustics to move cells and particles between microplates and as well as to form arrays of single living cells efficiently, quickly, flexibly and economically. Focused acoustic technology is the basis of the award-winning Labcyte® Echo™ 550 compound reformatter and the Echo™ 380 auditor shown for the first time this week at LabAutomation 2005.

Sunnyvale, CA, February 1, 2005– Labcyte Inc. announced today that it has been granted its 16th patent, US 6,849,423, for the rapid and gentle transfer of cells and particles, including beads, with acoustic energy. This patent describes the use of focused acoustics to move cells and particles between microplates and as well as to form arrays of single living cells efficiently, quickly, flexibly and economically. Focused acoustic technology is the basis of the award-winning Labcyte® Echo™ 550 compound reformatter and the Echo™ 380 auditor shown for the first time this week at LabAutomation 2005.

Dr. Elaine J. Heron, Chief Executive Officer of Labcyte Inc., said, “This technique is extraordinarily gentle to cells. Unlike pipette-based transfers that subject cells to considerable shear forces, cells transferred by acoustic techniques are stress free. In addition to transferring cells, the patent describes an integrated instrument and a method for the efficient and continuous sorting of cells based upon quantitative cellular properties. This continues our expansion in the application of acoustics in the life sciences.”

The Labcyte® Echo™ 550 compound reformatter uses the technologies described in US patents 6,666,541  and 6,802,593  as well as others in the company’s portfolio of 16 US patents. This system recently received an R&D 100 award for technical innovation and was the subject of scientific presentations on its use at pharmaceutical companies in the arena of high-throughput screening (HTS).
