The IHC-pro Immunohistochemistry Protocol
Tissue Preparation
Formalin fixation and embedding in paraffin wax
Tissue Sectioning
Make 4-µm sections and place on pre-cleaned and charged microscope slides.
Heat in a tissue-drying oven for 45 minutes at 60°C
Deparaffinization
Wash slides in 3 changes of xylene – 5 minutes each at room temperature.
Rehydration
Wash slides in 3 changes of 100% alcohol – 3 minutes each at room temperature.
Wash slides in 2 changes of 95% alcohol – 3 minutes each at room temperature.
Wash slides in 1 change of 80% alcohol – 3 minutes at room temperature.
Rinse slides in gentle running distilled water – 5 minutes at room temperature.
Antigen retrieval
Steam slides in 0.01 M sodium citrate buffer, pH 6.0 at 99-100°C - 20 minutes
Remove from heat and let stand at room temperature in buffer - 20 minutes
Rinse in 1X TBS with Tween (TBST) – 1 minute at room temperature.
Immunostaining
Do not allow tissues to dry at any time during the staining procedure.
Apply a universal protein block – 20 minutes at room temperature.
Drain protein block from slides, apply diluted primary antibody – 45 minutes at room temperature.
Rinse slides in 1X TBST - 1 minute at room temperature.
Apply a biotinylated secondary antibody (specific to the host of the primary antibody) - 30 minutes at room temperature.
Rinse slides 1X TBST – 1 minute at room temperature.
Apply alkaline phosphatase streptavidin – 30 minutes at room temperature.
Rinse slides in 1X TBST - 1 minute at room temperature.
Apply alkaline phosphatase chromogen substrate – 30 minutes at room temperature.
Wash slides in distilled water – 1 minute at room temperature.
Dehydrate
This method should only be used if the chromogen substrate is alcohol insoluble.
Wash slides in 2 changes of 80% alcohol – 1 minute each at room temperature.
Wash slides in 2 changes of 95% alcohol – 1 minute each at room temperature.
Wash slides in 3 changes of 100% alcohol – 1 minute each at room temperature.
Wash slides in 3 changes of xylene – 1 minute each at room temperature.
