- Increases confidence in pluripotency status by using 5 markers
Why Use Molecular Markers to Verify Human Stem Cell Pluripotency?
Stem cell pluripotency can be characterized functionally by their ability to differentiate into cells of the three vertebrate germ layers. However, functional verification is time-consuming, expensive, and is less conducive to routine stem cell culture screening or high-throughput analysis of stem cell pluripotency.
In addition to the abili ty to give rise to all cell types, a number of molecular markers have been identified to characterize the pluripotent status of stem cells. For example, human pluripotent stem cells express the cell surface proteins SSEA-4 and Alkaline Phosphatase and the transcription factors Oct-3/4 and Nanog.
Analyzing human stem pluripotency using marker antibodies:
- Promotes the identification and expansion of high quality, undifferentiated stem cell populations.
- Provides increased confidence in pluripotent status through the use of multiple markers.
- Defines the starting stem cell population to reduce experimental variation.
- Is a straightforward, cost-effective way to verify stem cell pluripotency.
This kit contains the following antibodies to verify human stem cell pluripotency:
Positive Markers
- Mouse Anti-Human Alkaline Phosphatase Monoclonal Antibody
- Goat Anti-Human Nanog Antigen-affinity Purified Polyclonal Antibody
- Goat Anti-Human Oct-3/4 Antigen-affinity Purified Polyclonal Antibody
- Mouse Anti-Human SSEA-4 Monoclonal Antibody
Negative Marker
- Mouse Anti-Human SSEA-1 Monoclonal Antibody
Each antibody is supplied as 25 µg; if reconstituted in 250 µL, this provides reagents sufficient for processing the equivalent of eight 300 µL immunocytochemistry samples or 25 flow cytometry samples at the recommended concentrations.
Stability and Storage
Reagents are stable for 12 months from date of receipt when stored in the dark at 2 °C to 8 °C.

Expression of Pluripotency Markers in Human Embryonic Stem Cells. Pluripotency marker expression was detected in immersion-fixed BG01V human embryonic stem cells using antibodies supplied in the Human Pluripotent Stem Cell Marker Antibody Panel (Catalog # SC008). Pluripotency marker expression was analyzed by dual immunofluorescence with the indicated primary antibodies supplied in the panel. The cells were stained using Catalog # NorthernLights™ (NL)493- and NL557-conjugated Secondary Antibodies (green and red, respectively). Where indicated, the nuclei were counterstained with DAPI (blue). View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips.

What is the difference between the Human Embryonic Stem Cell Marker Antibody Panel (Catalog # SC008) and the Human Embryonic Stem Cell Marker Antibody Panel Plus (Catalog #SC009)?
Catalog # SC008 was developed with a panel of antibodies that were significant stem cell markers at the time of release. As research on embryonic stem cells progressed, the number of markers of interest increased. Catalog # SC009 was later introduced to include antibodies for newly discovered markers, in addition to the antibodies from the original panel.
