TRA-1-81 Antibody (MA1-024) in ICC/IF
Immunofluorescent analysis of TRA-1-81 using anti-TRA-1-81 monoclonal antibody (Product # MA1-024) shows staining on the cell surface of human H9 human embryonic stem cells, indicating pluripotency. TRA-1-81 staining (green) and an overlay image of TRA-1-81 with DAPI (blue) is shown. H9 human embryonic stem cells were grown on matrigel coated chamber slides and fixed with formaldehyde prior to staining. Cells were probed with a Monoclonal antibody recognizing TRA-1-81 (Product # MA1-024) at a dilution of 1:20 overnight at 4 °C, washed with... View More

Target Information
TRA-1-81 is a cell surface antigen expressed along with SSEA-3, SSEA-4 and TRA-1-60 in human embryonic stem cells, embryonal carcinoma cells and induced pluripotent stem cells (iPS). These surface markers are down-regulated during the differentiation process. In contrast, SSEA-1 is absent in undifferentiated human stem cells but is present on the cell surface after retinoic acid mediated differentiation.
