Hey, Craig--
Very interesting--could you please post links for a few of these kits?
--Any publications out there on this approach? Any thoughts regarding
its possible applicability to shared facilities, where fool-proof
hardware (as well as easy-to-use software) are important? Or is this
approach better suited to an individual lab that wants its own
instrument but doesn't have $300K?
Thanks--
