-see also IFN-Gamma Elispot kit

-Coat ( e.g. ethanol activated PVDF plates ) with catching antibody* to cytokine; 50 Ál/well in coating buffer overnight at room temperature (RT).

-Wash the plate 4x with PBS; 1x with IMDM or with RPMI 1640.

-Incubate with blocking medium; 100 ul/well 1 h at 37oC.

-Empty plate and fill with cells (titration) and stimuli.

-Incubate at 37 oC in CO2 incubator. Incubation time depends on stimulus and cytokine under study.

-Wash the plate 5x with washing buffer.

-Add biotinylated antibody* to cytokine 100 ul/well in HPE and incubate 1h at RT on a shaker.

-Wash 5x with washing buffer.

-Incubate for 5min at RT with 100 Ál streptavidin-poly HRP (1/2000 in PBS + 2% milk) on shaker.

-Wash 5 x with washing buffer.

-Stain for ~10 minutes at RT with 3-amino-9-ethylcarbazol.

-Wash with H2O and dry.

Coating buffer: 0.1 M NaHCO3, pH 9.5

PBS 10 mM sodium phosphate 0.14 M NaCl pH 7.2

Culture medium RPMI 1640 or IMDM with 5 % FCS, pen/strep,

50 µM 2-mercaptoethanol; human transferin 20 µg/ml.

Blocking medium RPMI or IMDM containing 10 % FCS, pen/strep and 50 M 2-mercaptoethanol

Washing buffer PBS + 0.02 % Tween-20 (PT).

HPE Elisa High Performance buffer produced by CLB

3-amino-9-ethylcarbazol stock solution 10 mg/ml in dimethylformamide; For use in this assay dilute 1:30 in 50 mM Na acetate pH 5.0 and filter through a 0.45 µM filter. Then add 0.015 % H2O2.


To measure T cell cytokines (IL-2, IL-4, IL-13, IFN, TNFá and GM-CSF) the following stimuli can be used:

- Ca-ionophore (1 µM ionomycine) + PMA 1ng/ml. Stimulation overnight or

- anti-CD3 1 µg/ml + anti-CD28 1 µg/ml. Stimulation is for 2,3 or 4 days.

To measure monokine production (IL-1, IL-6, IL-8, IL-10, IL-12 and TNFá) stimulation can be carried out with LPS 1ng/ml or with SAC (1:1000).

For a number of monokines the plates are stimulatory by themselves.

-please inquire for other matched pair antibodies for human cytokines

-see some combinations under the individual cytokine antibodies which can be accessed through the cytokine table
