What Fluidigm Has Done with MSL

  • Enable four key life science applications
    • Tailor-made miniaturization for protein crystallization: enabled by over 400 valves.
    • High density PCR microprocessors for genotyping and gene expression: 1000s to 10,000s of nanoliter reaction volumes per chip.
    • Unique PDMS gas permeability enables multiple live cell handling capabilities: culture, perfuse, lyse and analyze in a single chip
    • Miniaturized, heterogeneous protein assays in self-programmable microprocessors: hundreds of valves and pumps per chip.
