Monosan AEC Substrate Kit, 515 ml

Intended use: AEC Substrate kit is intended for immunohistochemical and in situ-hybridisation staining procedures with horse radish peroxidase (HRP). AEC (3-Amino-9-ethylcarbazol) leads to the formation of a red-brown precipitate at the location of the target antigen or target nucleic acid. The precipitate is insoluble in aqueous mounting media and can be observed by light microscopy.

Reagents provided: 15 ml AEC Chromogen (liquid AEC concentrate)500 ml AEC Substrate Buffer

Storage and handling: 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. Do not use product after the expiry date. The working solution should be prepared freshly at the day of use. Once the two reagents are combined, the resulting solution is stable for up to three hours. Excess working solution needs to be disposed as hazardous substance. 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.

Reagent preparation: Add 20 µl AEC Chromogen (AEC concentrate) to 1 ml of AEC Substrate Buffer and mix thoroughly. Note: The colour intensity can be adjusted by decreasing or increasing the AEC concentration in the working solution.

Procedure: 1) Rinse the slide with wash buffer after the previous incubation step. 2) Apply the AEC working solution onto the slide. Incubate for 5-20 minutes. 3) Rinse with distilled H2O. 4) Counterstain with haematoxylin for about 30 seconds up to 5 minutes (depending on the desired staining intensity). 5) Rinse with distilled H2O. 6) Blueing in tap water for at least 5 minutes. 7) Mount with an aqueous mounting medium.

Expected results: During the reaction of the substrate with horse radish peroxidase in presence of the chromogen AEC, a red-brown precipitate is formed at the location of the target antigen or nucleic acid. The precipitate is insoluble in aqueous solvents and can be observed by light microscopy.
