Скачать или смотреть Combining Ion with DEPArray digitalized samples to resolve heterogeneity

Silicon Biosystems http://www.siliconbiosystems.com/ is a new company based in Italy that is developing a novel platform for solving the problem of heterogeneity of cells from tissues of many types. (For example, it is well-established http://www.ncbi.nlm.nih.gov/pubmed/22... that cancer is comprised of at least six cell types.) Their system uses microfabricated electrodes on a silicon chip married to a fluidic system, where a set of 9 electrodes form a di-electrophoretic ‘cage’ that enables single-cell trapping (as well as manipulation). These chips are called a DEPArray; more information about their technology can be found here. http://www.siliconbiosystems.com/depa...

Combined with a multi-fluor detection system in addition to a brightfield optical one, both epitope markers and cell morphology can be used to select out a few to tens of thousands of cells from a hetergeneous mixture of millions of cells. Their development group was able to generate Ion AmpliSeq Panel http://www.lifetechnologies.com/us/en... data from a pool of 300 disaggregated cells from an FFPE sample, and then use successfully lower numbers of cells (down to as few as 10) all within the timespan of 100 days.

Here’s an interview with Dr. Raimo Tanzi, where he discusses their experience with the Ion Torrent PGM™ System http://www.lifetechnologies.com/us/en....
