It is with great pride and immense pleasure that we introduce the Creative Bioarray QualiStem® Alkaline Phosphatase Live Staining Kit which provides a fast, simple and sensitive method for AP detection without fixing the cells. The reagent is nontoxic to the cells and the fluorescent signal will be discharged from the cells by exocytosis completely within two hours after removal of the staining solution, allowing the cell to be used for follow-up studies
