Automated 3D Cell-Based Assays

The Pu·MA System 3D has been designed to automate assays for your 3D cell models, organoids or spheroids. The Pu·MA System 3D maintains the cells in our specially designed flowchips to allow automated media or reagent exchanges for oncology, toxicity, metabolomics or neuroscience research.

PuMA System 3D Benefits

  • Automated “hands-off” workflow for complex assay protocol
  • Protected sample chamber to prevent cell damage
  • Perform in situ media exchanges, compound additions and supernatant sampling
  • Compatible with high content imaging and plate reader systems

Automated Assay Workflow

The Protein Fluidics’ Pu·MA System 3D streamlines your workflow to automate assays with minimal user handling. Transfer organoids to the flowchips, add media and reagents, place the flowchips plate into the system, select the assay protocol and press play. The system is touchscreen driven with an intuitive interface. Protein Fluidics Support is always available to answer questions.

How it works

The Pu•MA System and Flowchips use valve-less fluidic switching (VLFS) to precisely control fluid movement in a flowchip. The assay takes place in a protected chamber with microfluidic reagent/media exchanges that eliminates temperature and mechanical perturbations of the 3D cell models. Preloaded protocols exectue all fluid transfers and incubation steps.
