                 PELIPAIR (tm)  Human Cytokine Reagent Set

-manufactured by CLB Reagents


  Pelipair(tm) Elisa Reagent sets provide components for at least 1440 tests

-see recommended Elispot protocols below


Test principle and procedure

-The concept of the Pelipair reagent sets provides performance at the lowest price. the procedure recommended is the same as for our sucessful compact kits, after overnigth coating the assay is competed in 4 hours. The optimized and easy-to-follow protocol included in the sets warrants reliable assay results.

-When HEPE (High Performance ELISA, not included, order cat#RDI-M1940clb)  dilution bufer is used linear dose response curves in different matrices are ensured. High sensitivities can be achieved by using POLY-HRP (a polymer of HRP-Streptavidin, order cat#RDI-PHRPX-SA).

-For even more convenience additional buffers ad TMB subsrates are available as the Pelikine (tm) toolset, cat#RDI-M1980clb $188.00 or $156.00 when ordered with kit, sufficient for 3 X 96 weels)   (or TMB 1 liter cat#RDI-TMB-S-1L $312.0/1 Liter)


Contents:

Each kit contains sufficient reagents for at least 1440 samples (including calibration curves)

Components:

 5 vials coating antibody ( 5 X 375ul)

 5 vials human cytokine standard

 5 vials biotin-conjugated anti-human cytokine antibody ( 5 X 375ul)

-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.

Stimuli

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.
