the analysis of chromosomes stained by trypsin g-banding technique showed that , unlike mouse l-53 cells possessing unstable colchicine resistance , the b-82ch-9 and its b-82ch-9/cap derivative had neither chromosomes with long homogeneously staining regions ( hsrs ) nor other cytological manifestations of gene amplification , such as double-minute chromosomes and small chromatin bodies .
