SK-BR-3: Human Breast Cancer Cell Line (ATCC HTB-30)

SK 808


SK-BR-3 is a human breast cancer cell line that overexpresses the Her2 (Neu/ErbB-2) gene product. These cells display an epithelial morphology in tissue culture and are capable of forming poorly differentiated tumors in immunocompromised mice. The SK-BR-3 cells and products derived from it are used often as positive controls in assays for Her2. In addition, the cell line is also a useful preclinical model to screen for therapeutic agents targeting Her2 and to delineate mechanisms of resistance to Her2-targeted therapies.


This cell line was established in 1970 from the pleural effusion of a 43-year-old Caucasian female with malignant adenocarcinoma of the breast.
