Practical Microfluidics for Bioanalysis

3D Cell Technology

How it works

All assay reagents and organoids are loaded into the Pu•MA System 3D Flowchip wells. The flowchips are placed into the the Pu•MA System. Automated reagent exchange takes place through microfluidic channels and controlled by the Pu·MA System.

 

Compound Incubation

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.

Types of assay workflows

This technology can enable a range of assay workflows that result in multiparametric readouts from 3D cell models and organoids.

In Situ Supernatant Sampling

Organoids, media and reagents are loaded into the flowchips. The Pu·MA System performs the automated steps described below in the workflow.

Metabolomics Workflow

Spheroids or organoids, media and metabolites are loaded into the flowchips. The Pu·MA System performs the automated steps described below in the workflow. Once the automated treatment steps are completed, the organoids can be lysed in situ for downstream Mass Spectrometry analysis.

Sequential Drug Addition

Organoids, media and reagents are loaded into the flowchips. The Pu·MA System performs the protocol described below. Different concentrations of drug or compound can be added sequentially via automated steps, during which the samples can be visualized or measurements taken with minimal disruption to the organoid samples.

Immunofluorescence for Biomarker Detection

Biomarker detection in organoids, spheroids or tumoroids can be performed using immunofluorescence as shown in the workflow below. 

 

Organoids, primary antibody, secondary antibody, washes and nuclear staining are all loaded into the flowchips. Automated steps are performed within the Pu·MA System.
