荧光原位杂交（Fluorescence－in－situ－hybridization,FISH）原理
2）标本变性①将制备好的染色体玻片标本于 50oC培养箱中烤片2～3h。（经Giemsa染色的标本需预先在固定液中退色后再烤片）。②取出玻片标本，将其浸在70～75oC的体积分数70％甲酰胺/2×SSC的变性液中变性2～3min。③立即按顺序将标本经体积分数70％、体积分数90％和体积分数100％冰
荧光原位杂交（Fluorescence－in－situ－hybridization,FISH）（图）
实验原理荧光原位杂交（Fluorescence in situ hybridization FISH）是一门新兴的分子细胞遗传学技术，是20世纪80年代末期在原有的放射性原位杂交技术的基础上发展起来的一种非放射性原位杂交技术。目前这项技术已经广泛应用于动植物基因组结构研究、染色体精细结构变异分析、病

原子力显微镜（atomic－force－microscope,－AFM）工作原理
原子力显微镜是利用检测样品表面与细微的探针尖端之间的相互作用力（原子力）测出表面的形貌。探针尖端在小的轫性的悬臂上，当探针接触到样品表面时，产生的相互作用，以悬臂偏转形式检测。样品表面与探针之间的距离小于3－4nm，以及在它们之间检测到的作用力，小于10－8N。激光二极管的光线聚焦在悬臂的背面上。当
