Stemgent® StainAlive™ DyLight™ 488 Mouse anti-Human TRA-1-60 Antibody详细信息:
Product Overview
The Stemgent® StainAlive™ DyLight™ 488 Mouse anti-Human TRA-1-60 Antibody was screened on live, unfixed human embryonic stem (ES) cells using immunocytochemistry (ICC). This antibody was selected as the best conjugated TRA-1-60 antibody available for visualization of ES/iPS (induced pluripotent stem) cells, utilizing direct fluorescent staining and real-time imaging without fixation or killing the cells. This antibody format is useful for direct visualization of the reprogramming process to iPS colonies. For use on live cells, this antibody has been specifically formulated with low endotoxin and no sodium azide and is confirmed to be free of bacteria, fungi, mouse virus and mycoplasma as tested. The live ES cell morphology, proliferation and expression of pluripotency markers did not change after staining with this antibody. Clone TRA-1-60 reacts with a pluripotent-stem-cell-specific antigen expressed on undifferentiated human embryonic stem (ES) cells, embryonal carcinoma (EC) cells, and embryonic germ (EG) cells. The expression of TRA-1-60 on human ES cells is down-regulated upon differentiation. The TRA-1-60 antibody recognizes a neuraminidase-resistant carbohydrate epitope expressed on podocalyxin, a member of the CD34-related family of sialomucins. Podocalyxin is a transmembrane glycoprotein, which has been implicated in the development of aggressiveness in a variety of cancers, including breast and prostate cancer.
