IHC-P protocol
- Deparaffinize the section in 3 changes of xylene, 5 minutes each.
- Wash the section in 96%, 80% and 70% benzyl alcohol for 5 minutes each.
- Rinse in distilled water.
- Block the endogenous peroxidase by incubating the tissue in 3% hydrogen peroxide (H2O2) for 10 minutes.
- Wash in distilled water.
- For antigen retrieval use one of the following procedures: A) Immerse the slide in Tris-EDTA buffer, pH 9.0, 0.05% Tween- 20*, and incubate in microwave (600W) for 10 minutes, or B) Immerse the slide in citrate buffer, pH 6.0, 0.05% Tween-20**, and incubate in microwave (600W) for 10 minutes.
- Remove the staining to room temperature and let the slide to cool for 15 minutes.
- Rinse in distilled water.
- Wash in 0.05 M Tris-HCl , pH 7.6 buffer supplemented with 0.5% of Tween-20 (buffer A) for 5 minutes.
- For concentrated products: Incubate the section with primary antibody diluted in buffer A at the dilution 1:100 - 1:200 for 1 hour in the closed wet chamber.
For RTU products: Incubate the section with primary antibody (ready to use) for 1 hour in a closed wet chamber.
- Wash twice 5 minutes with buffer A.
- Apply the secondary antibody (the protocol depends on the supplier), and proceed to standard immunohistochemistry protocol (HRP – Peroxide – DAB).
- Wash twice 5 minutes with buffer A.
- Apply the chromogen (DAB), 10 minutes.
- Wash in water – 10 minutes.
- Stain in hematoxylin for 5 minutes.
- Wash in water – 10 minutes.
- Dehydrate the section in 2 changes of 96% benzyl alcohol for 5 minutes each.
- Wash the section in 2 changes of xylene for 2 minutes each.
- Mount the slide for observation.
Formalin-fixed and paraffin-embedded human skin cells (4 μm) stained with anti-CD1a (DB 071) antibody show strong positive immunostaining of Langerhans cells in epidermis.
