Abstract
This protocol is to demonstrate how to run a standard plate-based assay on the flow cytometer to produced appropiate concentations of the various analytes to be measured.
Guidelines
This assays is specifally designed for the ATTUNE NxT flow cytometer and the Milli-metabolic bead assays

Troubleshooting
Before start
Setting up instruments correctly is a critical step in any assay
Check the waste and
If the waste is full, disconnect the tank and dispose of the waste down the sink with running water. Add 200 mL of 5% bleach to the tank and reconnect to the Attune NxT. Fill the Focusing Fluid tank from the focusing fluid cube.
Check and fill as needed the shutdown solution reservoir and the wash solution reservoir.
Also check the waste and focusing fluid reservoirs at the plate sampler station.
At the workstation, click on instrument > start-up at the top of the screen.
When start-up is complete, the indicator lights at the instrument will be green.
Run the performance test.
When the plate finishes, right click on the experiment.
