Immunofluorescent analysis of SSEA4 using anti-SSEA4 monoclonal antibody (Product# MA1-021) shows expression in human teratocarcinoma NCCIT cells (shown in green) but not in negative control HeLa cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature. Cells were blocked with 1% Blocker BSA (Product #37525) for 15 minutes at room temperature. Cells were probed with a mouse monoclonal antibody recognizing SSEA4 (Product# MA1-021), at a dilution of 1:50 for at least 1 hour at room temperature. Cells were washed with PBS and incubated with DyLight 488 goat-anti-mouse secondary antibody (Product# 35503) at a dilution of 1:400 for 30 minutes at room temperature. Nuclei (blue) were stained with Hoechst 33342 dye (Product# 62249). Images were taken on a Thermo Scientific ArrayScan at 20X magnification.

MA1-021 has been successfully used in immunofluorescence and flow cytometry with human samples.
Stage-specific embryonic antigen 4 (SSEA-4) is a cell surface antigen, expressed along with SSEA-3, TRA-1-60 and TRA-1-81 in embryonic stem cells, embryonal carcinoma cells and induced pluripotent stem cells (iPS). In human cells, these surface markers are down-regulated during the differentiation process, while SSEA-1 is absent in undifferentiated human stem cells and upregulated on the cell surface after retinoic acid mediated differentiation. Conversely, in mouse stem cells, SSEA-1 expression decreases with differentiation while SSEA-3 and SSEA-4 expression increase.
