Product Type Assay & Detection
Protocol Paraffin-embedded tissue sections are first deparaffinised and rehydrated. Background staining caused by unspecific binding of the primary antibody or the secondary antibody in the AP One-Step Polymer is minimized by incubation with a protein blocking solution. This step can be omitted if the primary antibodies are diluted in an appropriate buffer. The next step is incubation with the specific primary antibody. After washing, the AP One-Step Polymer is applied and incubated. Any excess of unbound polymer is thoroughly washed away after incubation. The addition of the chromogenic substrate starts the enzymatic reaction of the alkaline phosphatase which leads to colour precipitation where the primary antibody is bound. The colour can be observed with a light microscope. The chromogen used determines the colour. The chromogen Permanent AP Red leads to the formation of a magentared product of reaction at the place of the target antigen. Other suitable chromogens are Fast Red (magenta-red), New Fuchsin (magenta-red), or NBT (blue-black) with its substrate BCIP. Staining procedure 1. Blocking Solution (This step is optional.) 5 min. 2. Washing with wash buffer 1 x 2 min. 3. Primary antibody (optimally diluted) or negative control reagent 30-60 min. 4. Washing with wash buffer 3 x 5 min. 5. AP One-Step Polymer anti-Mouse/Rabbit/Rat 30 Min. 6. Washing with wash buffer 3 x 2 min. 7. Permanent AP Red, Fast Red, NBT/BCIP or New Fuchsin 10 - 20 min. (Controlling the colour intensity via light microscope is recommended.) 8. Stopping the reaction with distilled H2O when the desired colour intensity is attained 9. Counterstaining and blueing 10. Mounting: aqueous with Fast Red, permanent with Permanent AP Red, NBT/BCIP or New Fuchsin
