Tissue culture supernatant was cross flow concentrated.
The monoclonal antibody that defines SSEA-3 was derived by fusing cells of the murine myeloma cell line SP2/0 with the spleen cells of a Fisher rat immunized with 4-8-cell-stage zonapellucida-free embryos from randomly bred mice.

SSEA3 also known as Stage-Specific Embryonic Antigen-3 is a glycosphingolipid with a molecular mass not specifically defined due to its lipid nature. This antigen is expressed on the surface of pluripotent stem cells particularly human embryonic stem cells and some germ cells. SSEA3 belongs to the globoseries of glycolipids and is widely used as a marker for undifferentiated cells. The expression of SSEA3 decreases as these cells undergo differentiation which makes it useful in studying stem cell biology and early development processes.
SSEA3 plays a role in cell adhesion and signaling during early embryogenesis. It does not form a complex itself but exists in the cell membrane contributing to interactions with other molecules or possibly engaging in signaling processes essential for cell proliferation and maintenance of stemness. The role of SSEA3 as a marker in detecting undifferentiated cells uncovers its importance in maintaining specific cell states.
SSEA3 may influence cellular pathways that govern stem cell maintenance and differentiation. Though not directly a pathway component it associates with proteins involved in pluripotency regulation like the Wnt and Notch pathways which are important for determining cell fate and growth. These pathways involve connections to proteins such as beta-catenin in the Wnt pathway which can influence stemness and cellular development.
Alterations in SSEA3 expression have been related to certain cancers and stem cell-related diseases. SSEA3 is sometimes found in higher levels in cancers that exhibit stem cell-like characteristics such as certain teratocarcinomas. It connects to proteins implicated in oncogenesis through shared expression patterns in tumors and stem cells like the Oct4 protein which is known for its role in maintaining stem cell properties and is often reactivated in cancer cells.

Terms & Conditions.
Human induced pluripotent stem cells (iPSCs) stained with ab16286 (red fill). In brief, iPSCs were fixed in 4% formaldehyde (methanol-free) for 15 min at 25°C. Cells were then incubated with the antibody (ab16286, 1/50 dilution) for 30 min at 4°C. The secondary antibody used was Alexa Fluor® 647 goat anti-rat IgG at 1/2000 dilution for 30 min at 4°C. iPSCs differentiated for 28 days toward a cardiomyocyte lineage (blue fill) were used as a negative control. Acquisition of >30,000 total events were collected using a 100mW solid state diode laser (640nm) and 670/30 bandpass filter.
Anti-SSEA3 antibody, ab16286 can be used as a marker of Embryonic Carcinoma cells in Flow Cytometry/FACS. The top histogram (A) shows undifferentiated NTERA2 cells (i.e. without retinoic acid) recognised by ab16286. However, upon differentiation (by the addition of retinoic acid 10-5M for 7 days), the antibody lost the ability to recognise these cells as shown in the bottom histogram (B).
The image shows cell membrane staining of 2102Ep human embryonic carcinoma cells using SSEA3 specific antibody ab16286.
