Monosan AEC Single Solution

Intended use: AEC Single Solution is a ready-to-use solution 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. AEC Single Solution is especially useful when a high sensitivity is desired.

Reagents provided: 8 ml AEC Single Solution (ready-to-use)

Storage and handling: The solution should be stored at 2-8°C without furt her dilution. Please store the reagent in a dark place and do not freeze it. Under these conditions the solution is stable up to the expiry date indicated on the label. Do not use product after the expiry date. AEC Single Solution is a ready-to-use solution. Preparation of a working solution as in other chromogenic substrates is not necessary. 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: The solution is ready-to-use. AEC Single Solution can be used directly from the refrigerator and should be stored again at 2-8°C aft er use. When using the small package (8 ml MON-APP169) please directly drop from the bottle. When using the 100 ml package (MON_APP?) please transfer up to 8 ml of the AEC Single Solution into one of the provided dropper bottles. The transferred solution is stable for many weeks if stored at 2-8°C. The vo lume required for several staining runs should be transferred so that the 100 ml stock bottle has to be opened only a few times. If you would like to pipette the solution use a clean vial from which you pipette. Remaining quantities should not be filled back into the bottle but disposed as hazardous material.

Procedure: 1) Rinse the slide with wash buffer after the previous incubation step. 2) Apply the AEC Single Solution to the slide. Incubate for 3-6 minutes. (Incubation time can be extended up to 30 minutes, if desired.) 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.
