Abstract |
We investigated the cytogenetic characteristics of male black-striped field mouse (Apodemus agrarium) in Korea. Chromosome slides were obtained from blood cell cultures which were synchronized with thymidine blocking or not. In the chromosome slide which synchronization with thymidine blocking was employed on, the GTG(G bands by trypsin using Giemsa)-bands of high resolution were observed. The male black-striped field mouse has 48 chromosomes composed 46 autosomes and XY sex chromosomes. The centromeric regions of autosomes were positive to GTG-banding. According to this investigation, thymidine blocking in cell culture process was useful to get lengthened chromosomes. It may be necessary to employ RBG-banding technique to investigate complementary band patterns between R- and G-banding in black-striped field mouse. |
