Alkaline Phosphatase Live Stain is a stem cell imaging product that allows users to differentially stain pluripotent stem cells (PSCs). The dye is a cell-permeable fluorescent substrate for alkaline phosphatase (AP) that is non-toxic to cells, diffusing out over the course of two hours. The Alkaline Phosphatase Live Stain consists of 50 μL of a 500X fluorescein-based dye in DMSO, sufficient for staining two 24-well plates, four 6 cm dishes or two 10 cm dishes.

This Alkaline Phosphatase Live Stain allows you to:

• Identify pluripotent stem cells with a strong signal above background
• Stain PSCs typically in 20 minutes or less
• Use the first alkaline phosphatase stain marketed that maintains cell viability

Alkaline Phosphatase Pluripotent Stem Cell Detection Method
AP is a phenotypic marker of PSCs, including undifferentiated embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and embryonic germ cells (EGCs). While AP is expressed in most cell types, its expression is highly elevated in PSCs. AP staining has therefore been used to differentially stain PSCs to easily distinguish them from mouse embryonic fibroblasts (MEFs) used as feeders and parental fibroblasts commonly used in reprogramming experiments.

Screen for Pluripotency Without Sacrificing Precious Colonies
The Alkaline Phosphatase Live Stain is ideal for screening colonies during early stages of the reprogramming workflow since the stain maintains stem cell viability. It can also be used in later stages as a negative selection tool for identifying undifferentiated cells.

Stain Cells Quickly
The Alkaline Phosphatase Live Stain utilizes an easy, non-permanent, cell-viable protocol for identifying PSCs in your experiments. Simply dilute the dye in media, apply to cells, gently wash, and the cells are ready for fluorescent imaging.

Frequently asked questions (FAQs)

How can I prevent poor or dim staining when using Alkaline Phosphatase Live Stain?

Serum or serum replacement components in the growth medium may cause background and this can result in poor or dim staining. After the removal of the growth medium, gently wash the culture with pre-warmed DMEM/F-12 (Cat. No. 10565-018) for 5 minutes. Aspirate and repeat once before adding the AP Live Stain. To further decrease background staining, perform 3 separate washes of 5 minutes each with DMEM/F-12 for a total of 15 minutes following the staining, and visualize immediately.

How should Alkaline Phosphatase Live Stain be stored?

Store AP Live Stain at -20 degrees C in the freezer and thaw at room temperature. Avoid repeated freeze/thaw cycles and aliquot the AP Live Stain into smaller volumes if necessary. Always protect from light and avoid extended exposure at room temperature and atmospheric conditions.

Can I use Alkaline Phosphatase Live Stain in my reprogramming experiments?

AP Live Stain is ideal for screening colonies during early stages of reprogramming since it selectively stains PSCs while maintaining cell viability. It can be used in later stages of reprogramming to identify undifferentiated cells for the selection of iPSCs for further cultivation. AP Live Stain was developed specifically for use on live cultures for cell maintenance and is qualified to be free of mycoplasma and bioburden, and exhibits extremely low endotoxin levels.

How long should I wait before using Alkaline Phosphatase Live stain on my cells again?

Colonies may be restained as early as 24 hours after the initial staining. It is recommended that cells are allowed to recover properly to obtain consistent results.

How many times can the same cells be stained with Alkaline Phosphatase Live Stain?

AP Live Stain can be used daily throughout the life of a culture without any adverse effects.
