We are looking for a reliable source of BG1 ovarian carcinoma cells (estrogen- sensitive). According to Cellosaurus (http://web.expasy.org/cellosaurus/CVCL_6570) most of the stocks are contaminated with MCF-7 cells, but not the original (French) source. However, this particular cell line is not available through major public/commercial repositories and the people we have tried to contact concerning this cell line do not respond. Any useful tips are welcome.
