SSEA-4 is expressed on the surface of human embryonal carcinoma (EC) cells (the pluripotent stem cells of teratocarcinomas), human embryonic germ cells (EG), and human embryonic stem cells (ES). Expression of SSEA-4 is down-regulated following differentiation of human EC cells. In contrast, the differentiation of murine EC and ES cells may be accompanied by an increase in SSEA-4 expression (1-4).

Kit Summary
To detect SSEA-4 expression in live cells by immunocytochemical staining.
Why confirm marker expression in live cells before colony selection?
Maintaining pluripotent human embryonic stem cells and deriving induced pluripotent stem cells require colony selection and cell expansion. Picking colonies that contain pluripotent stem cells is typically achieved by manually analyzing colony morphology. Unfortunately, this critical process is time-consuming and labor-intensive.
In addition, morphology-based colony selection does not consistently guarantee pluripotent starting populations, since cells can fail to be fully reprogrammed or can naturally differentiate within a colony.
To address this need, R&D Systems offers GloLIVE™ antibodies that allow researchers to confirm stem cell marker expression in live cells before colony selection.
Live pluripotent stem cell imaging:
- Promotes the selection of high quality, undifferentiated stem cell colonies to reduce experimental variation.
- Verifies stem cell pluripotency in 30 minutes, ensuring efficient use of time and reagents.
- Allows for the continued culture of pluripotent cells with no adverse effects on cell proliferation or stemness following staining.

Scientific Data Images for GloLIVE Human/Mouse SSEA-4 NL557 Live Cell Antibody
Detection of SSEA-4 in Live BG01V Human Embryonic Stem Cells.
The stem cell marker SSEA-4 was visualized in live BG01V human embryonic stem cells using a GloLIVE NL557-conjugated Mouse Anti-Human/Mouse SSEA-4 Monoclonal Antibody (Catalog # NLLC1435R; red). The cells were counterstained with Hoechst 33342 (blue). Positive staining for SSEA-4 in human stem cells is an indicator of pluripotency.Formulation, Preparation, and Storage

Live Cell Immunocytochemistry Procedure Overview
To ensure sterility of cultures, all steps should be performed under sterile conditions.
- Add fluorochrome-conjugated primary antibody in appropriate culture media to cells.
- Incubate for 30 minutes.
- Replace with fresh culture media.
- Visualize using a fluorescence microscope.
Note: Culture with GloLIVE antibodies does not appear to affect cell proliferation or stemness as assayed by proliferation curves for 3 days post-antibody incubation and expression levels of SSEA-4 and Oct-3/4.

Q: What is the recommended starting confluence to observe staining?
A: The optimal confluence would depend on the purpose of the staining. If the plan is to use all the cells in the flask after they have proliferated, then one can wait for the cells to become confluent or almost confluent (80-90% confluent) and then check the staining. If the goal is to to check on the cells mid-way through their growth and there are sufficient cells in the flask, one could check the staining then as well. The staining is not dependent on how many cells are in the flask, as long as there are sufficient cells.
