dna ladder meaning in English
梯状条带
Examples
- Dna ladder bands with a periodicity of about 200 bp were clearly seen in agarose gel electrophoresis pattern
琼脂糖凝胶电泳基因组dna可见到约以200bp为间隔的dna梯状( ladder )条带。 - 0 . 1 - 5 . 0 mmol / l al can induce dna ladders in the root - tips ( treated for 8 h ) and suspension cells ( treated for 24 h ) of barley , but no apoptotic bodies were observed
0 . 1 - 5 . 0mmol / l铝处理大麦根尖8h或悬浮细胞24h均产生了梯状dna ，但未观察到凋亡小体的形成。 - The morphology of the apoptotic cells and its transformation were observed under electron microscope . the typical dna ladder was appeared in the dna fragments isolated from the apoptotic cells , which indicated that the dna was splited by endonuclease between the nucleosome subunits
进而在电子显微镜下观察到典型凋亡细胞形态，以及在不同as _ 2o _ 3浓度下培养不同时间，还可观察到细胞凋亡早期、中期、晚期的改变。 - This review focuses on the techniques and methods that are currently used for the detection of apoptosis , such as morphological observation , fluorescence staining , dna ladder , caspase activity , etc , and on the evaluation of the advantages and limitations of these methods
本文综述了常用的细胞凋亡检测技术与方法的基本原理，如形态学观察、荧光素染色、 dna阶梯、半胱氨酸天冬氨酸蛋白酶活性的检测等，并对各种方法的优点及局限性做一简要比较。 - The mechanisms of such treatment have been proposed as inhibition of proliferation and angiogenesis , as well as induction of differentiation and apoptosis , as has been tested by various in vivo and in vitro experiments . in our experiments , it has also been demonstrated that after the treatment of arsenic trioxide , the k562 cells has undergone major morphological changes , which included nuclear shrinkage , membrane bleb and scattered apoptotic bodies . dna gel electrophoresis also discovered that the typical " dna ladder " phenomena in the treatment group , while the control group showed the regular genomic banding
我们在实验中观察到as _ 2o _ 3作用人红白血病k562细胞后，细胞生长明显变缓，部分细胞出现皱缩、染色质浓聚及胞膜起泡现象，部分细胞胞膜破裂，在其周围有致密的凋亡小体出现， dna电泳出现典型的凋亡“梯状”带，提示as _ 2o _ 3能有效抑制k562细胞生长，诱导k562细胞凋亡。
