From: Is MMTV associated with human breast cancer? Maybe, but probably not
Detection of MMTV DNA in human benign and breast cancer specimens. a and b are ethidium bromide stained gels, and c is a Southern hybridization using the MMTV “clinical” primers and probe. NC is no DNA target added; PC is the positive control containing 100 copies of MMTV DNA extracted from Mm5Mt cells; and DM is the DNA markers. Lanes 4, 8 and 9 are benign breast tissue samples, while lanes 1, 2, 3, 5, 6, 7, 10, 11 and 12 are malignant breast tissue samples. Lane 12 is sample 40,412
