Permanent AP-Red Kit, 1 Kit (500 ml/5,000 tests)

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.
