| Application notes | Paraffin-embedded tissue sections are first deparaffinised and rehydrated. Endogenous peroxidase activity in the tissue may cause non-specific staining. This enzyme activity can be blocked by incubation with 3% H2O2-solution (“Peroxide Block”). Background staining caused by unspecific binding of the primary or secondary antibody is minimized by incubation with a protein blocking solution (“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 biotinylated secondary antibody is applied and incubated. This antibody functions as a link between primary antibody and the streptavidin-horse radish peroxidase-conjugate (“Streptavidin-HRP-Conjugate“). A second washing is followed by the application of this conjugate. It binds to the biotin at the secondary antibody. Any excess of unbound streptavidin-HRPconjugate is thoroughly washed away after incubation. The addition of the chromogenic substrate starts the enzymatic reaction of the horse radish peroxidase 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 AEC (included only in kit MON-APP132) leads to the formation of a red-brown product of reaction at the place of the target antigen. The chromogen DAB (included only in kit MON-APP133) forms a dark brown precipitate. |
| Storage | The solutions should be stored at 2-8°C without fur ther dilution. Please store the reagents in a dark place and do not freeze them. Under these conditions the solutions are stable up to the expiry date indicated on the label. They should not be used after the expiry date. A positive and a negative control have to be carried out in parallel to the test material. If you observe unusual staining or other deviations from the expected results which could possibly be caused by the kit reagents, please contact our technical support |
