The chromosomes of L1210 mouse leukemia cells: G-banding, C-banding, and Ag-staining. 1984

M Seifertová

The karyotype of L1210 mouse leukemia cells was studied using G-banding, C-banding and Ag-staining methods. In modal chromosome number and G-banding patterns we were interested in the differences between line A and B carried by DBA/2 mice in our laboratory. Both lines had the modal chromosome number of 38. Lines differed significantly in the average number of nine chromosomes per karyotype, whereas in marker chromosomes significant difference was found only in M2 and M6. Marker M1 t(5, 12) was present in 95% of cells in line A and 100% of cells in line B. More than 50% of cells in both lines contained M2, M11, M13 and M14. X-Chromosome and chromosome No. 4 were most frequently absent. More than 80% of cells in both lines had only one chromosome No. 5, and trisomy of chromosome No. 15 was found in 50% of cells in line A and 40% in line B. Values for disomy were low for all chromosomes in both lines. Marker M1 t(5, 12) possessed C-banding material at the proximal end of translocated chromosome No. 5 and NOR at the proximal end of translocated chromosome No. 12. Marker M2 t(1, 12) without NOR had the C-banding material located at the proximal end of chromosome No. 1.
