Practical Microfluidics for Bioanalysis

The Pu·MA System

Automated 3D Cellular Assays

The Pu•MA System is a practical and affordable benchtop instrument, ideal for running physiologically complex spheroid and microtissue assays for toxicity testing and oncology discovery as well as diabetes and metabolic disease research. The system fits into standard incubators and provides gas exchange to the cell sample chambers. Complex assay protocols can be setup to automatically run from hours to days.

Pu·MA System Benefits

 

Mimic in vivo conditions

Perform multi-dosing protocols and multiple media exchanges, all within your lab incubator, for extended periods.

Adapt to new assay needs

One system and flowchip accommodates a broad range of cell-based and biochemical assays.

Handle liquids gently

Spheroids and microtissues reside in a protective chamber within the well, shielding cells from flow-induced sheer forces.

Detect results easily

Clear-bottom wells enable use of imagers and point-readers for cell-based and biochemical assays.

Walk-away convenience

Protocols are fully automated, even with multiple media/reagent exchanges.

How it Works

All assay reagents are loaded into reservoirs and then moved one at a time through microfluidic channels by the Pu·MA System. Preloaded protocols execute all fluid transfer and incubation steps. The system incorporates patented valve-less fluidic switching (VLFS) to precisely control fluid movement in a flowchip. Use of microfluidics reduces both required incubation times and reagent volumes.

3D Cell Assay Workflows

Spheroids or microtissues are loaded into a “protective chamber” in sample wells

  • 32 samples can be loaded per plate

Reagents are loaded into adjacent reservoir wells

  • Up to six reagents or media
  • Load with standard single or multichannel pipettes

Pu·MA System automatically performs all reagent transfers

  • Media exchange, compound addition, etc.
  • Separate reservoir for waste media and reagents

Enables a wide range of assay readouts

  • Cell supernatant sampling
  • High content imaging
  • ATP viability
  • Metabolomic sampling
