【解析】绝大部分RNA分子都是线状单链,但是RNA分子的某些区域可自身回折进行碱基互补配对,形成局部双螺旋.在RNA局部双螺旋中A与U配对、G与C配对,除此以外,还存在非标准配对,如G与U配对.RNA分子中的双螺旋与A型DNA双螺旋相似,而非互补区则膨胀形成凸出(bulge)或者环(loop),这种短的双螺旋区域和环称为发夹结构...
本品是一种高敏感的核酸染色试剂,可以对RNA或者是单链的DNA进行染色。使用300nm透射光显影的情况下,非变性凝胶中检测核酸的灵敏度可以达到5×10-7克。与传统的EB染料相比,SYBR Green II RNA染料的灵敏度更高,可以应用于杂交前RNA质量的检测,同时不会影响后续的转膜,还可应用于变性梯度凝胶电泳(DGGE)和单链构象...
