Monosan Permanent AP-Red Kit, 1 Kit (125 ml/1,250 tests)

Intended use: Permanent AP Red Kit is developed for immunohistochemical and in situ-hybridisation staining procedures with alkaline phosphatase. Permanent AP Red leads to the formation of a magenta-red precipitate at the location of the target antigen or target nucleic acid. The precipitate is insoluble in aqueous and organic solvents and can be observed by light or fluorescence microscopy.

Reagents provided: 125 ml Permanent AP Red Buffer 2 ml Permanent AP Red Chromogen 1 Dilution Vial

Storage and handling: The solutions should be stored at 2-8°C without further 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 prepared is stable for about 60 minutes and should therefore be used directly after preparation. Excess working solution should be discarded. 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: Reagent preparation (Preparation of the working solution) 1) Pipette 2.5 ml AP Red Buffer into the provided dilution vial and let it come to room temperature. The chromogen should still be kept cool. 2) Directly prior to use add 1 drop of Permanent AP Red Chromogen into the buffer. Mix thoroughly. 3) The solution is stable for about 60 minutes. Preparation should be done directly before use. Make sure to pipet the chromogen/substrate mix on the last slide of the staining run within 40 min after mixing. If you want to prepare other quantities of the working solution, please use same ratio AP Red Buffer and Chromogen

Procedure: 1) Rinse the slide with wash buffer after the previous incubation step. 2) Apply freshly prepared Permanent AP Red working solution onto the slide. Incubate for 10 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) Dehydrate through a graded series of ethanol and clear in xylene. Mount with a permanent mounting medium. Note: It is also possible to mount Permanent AP Red with aqueous mounting media.

Expected results: During the reaction of the substrate with alkaline phosphatase in presence of the chromogen Permanent AP Red, a magenta-red precipitate is formed at the location of the target antigen or nucleic acid. The precipitate is insoluble in aqueous and organic solvents and can be observed by light or fluorescence microscopy (Texas Red filter).
