Analysis of genomic DNA from rodent cell lines with a specific rat primer pair targeting rat β-actin. PCRs were performed with oligonucleotid primers act-rat-F and act-rat-R which are specific for rat. Amplified DNA fragments were detected after ethidium bromide staining of a 1.2% agarose gel. Lane 1, PC-12 (ACC 159); lane 2, MC3T3-E1 (ACC 210); lane 3, C2C12 (ACC 565); lane 4, RGE (ACC 262); lane 5, RBL-2H3 (ACC 312); lane 6, A-10 (ACC 132); lane 7, BHK-21 (ACC 61). H, Hamster; M, Mouse; R, Rat. The arrow indicates the DNA molecular weight marker of 500 bp
