摘要: 由八字地老虎Xestia c-nigrum血细胞建立了一株细胞系,命名为NEAU-Xc-960716H,原代培养90余天,现已传至70余代。细胞多为圆形,部分梭形,细胞群体倍增时间约为63 h。具有典型的鳞翅目昆虫染色体特征,数量多,形态为短杆状和球形。酯酶同工酶谱为5条主带,与同种昆虫(八字地老虎)的胚胎细胞系(NEAU-Xc-730E)酯酶图谱稍有不同,而与草地夜蛾细胞系(IPLB-SF-21)的酯酶图谱完全不同。该细胞系可以被八字地老虎核型多角体病毒XcNPV感染,但感染率较低。

Abstract: A new insect cell line, NEAU-Xc-960716H, was established from Xestia c-nigrum larval hemocytes through successive passage over 70 generations since July 1996. The cells were classified into two types: spherical and spindle. The population doubling time of the cell line was about 63 hours. The chromosomes were condensed short rods and round, typical in lepidopteran cell lines. The isozyme pedigree of esterase was different from the embryonic cell lines NEAU-Xc-730E of Xestia c-nigrum and IPLB-SF-21. The cell line was susceptible to Xestia c-nigrum nuclear polyhedrosis virus (XcNPV), although at a low level.
