Diabetic Mouse Mammary Epithelial Cells from Creative Bioarray are isolated from the breast of Diabetic (db/db) mice. Diabetic Mouse Mammary Epithelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based coating solution for 2 min and incubated in Creative Bioarray�s Culture Complete Growth Medium generally for 3-7 days. Cultures are then expanded. Prior to shipping, cells at passage 3 are detached from flasks and immediately cryo-preserved in vials. Each vial contains at least 0.5x10^6cells per ml. The method we use to isolate primary epithelial cells was developed based on a combination of established and our proprietary methods. Cells are incubated with EpCAM-1 (CD326) antibody, following the application of magnetic beads pre-coated with secondary antibody.
