日本血吸虫染色体核型分析及C带和G带的制备
Analysis of Karyotype and Preparation of C-band and G-band in Schistosoma japonicum
【摘要】 收集日本血吸虫成虫,常规气干法制备血吸虫染色体,改进的BSG法制备C带,胰酶消化法制备G带,分析其染色体核型和C带、G带带型特征。研究表明其核型公式为2n=4m+6Sm+4St+2性染色体,C带带型公式为2n=5CI++4CI++3CI+2CT+2CT+,各对染色体显示出特征性的G带。
【Abstract】 Chromosomes of Schistosoma japonicum were prepared by usual air drying method, C-band and G-band were made by modified BSG method and enzyme digestion method respectively. Results showed that the karyotype of S. japonicun was 4m+6Sm+4St+2sex chromosome and the C-band formula was 2n= 5CI++4CI++3CI+2CT+2CT+.
