Instrumentation needed:
Sterile plastic disposables
Laminar Flow Hood
Humidified 37°C, 5% CO2 incubator
Isolate TEFF and TREG with Miltenyi Kit according to the protocol PBMC- 03.
Count both TEFF and TREG following the appropriate protocol (CELL COUNT- 02 or CELL COUNT- 03).
Use sterile 96-well round bottom plates.
Note
[Consider that these plates can contain a volume of maximum 250µL]

Resuspend TEFF and TREG in SOLUTION- 13 at a concentration of 1x106/mL.
According to the experimental design, activate a desired number of wells containing TEFF cells with PHA 5µg/ml (final concentration) and IL-2 40 ng/mL (final concentration) by diluting the stock aliquots. Leave also wells of TEFF unstimulated (resting control).
Put TEFF-CPD labeled cells and TREG cells in the 96-well plate at a ratio of 1:1(for example, 0.1x106 TEFF + 0.1x106 TREG) and activate the cells il the well directly (see step 7 for concentrations): include 1 control co-culture (not treated with test substance) and treated co-cultures (+test substance) according to your experimental design.
Include also a culture of resting and activated TEFF alone (for example 0.2x106per well), as control for the subsequent ELISA test.
Put the plate in a 37 °C incubator for 48 hours.
At the end of cell culture, collect the supernatant in eppendorf tubes (1.5mL) and centrifuge them at 1200 x g, Room temperature, 00:05:00 in order to eliminate any residual cells.
