MATERIALS:
- ELISA plates NUNC ref: 442404 Thermoscientific
- Coating buffer: sodium carbonate (pH 9.6)
- Recombinant Human NF155 protein
- RAH-HRP IgM secondary antibody, Dako P0215
- RAH-HRP IgG secondary antibody, Dako P0214
- TMB solution (BioLegend)
- Non-fat dry milk
- H2SO4
- PBS-Tween 0.1%
PROCEDURE:
- Coat ELISA plate with NF155 protein (5ugr/mL) in carbonate/bicarbonate buffer (pH 9.6) and incubate O/N at 4ºC rocking.
- The day after, wash plate 3xPBS-Tween 0.1% and block with milk 5% in PBS-Tween for 1 hour, 200uL per well).
- Add patients sera diluted 1/100 (200uL/well) and incubate 1h at RT.
- Wash 3xPBS-Tween 0.1%
- Add secondary antibody RAH IgM 1/2000 in milk 5% (except for the positive control, using RAH IgG 1/5000) and incubate 1h at RT.
- Wash 3xPBS-Tween
- Add TMB solution 10′
- Stop reaction with H2SO4
- Lecture at 450-620 nm.
