Inoculate a 5 ml culture with a single colony from a YAC-containing strain of yeast and grow until saturated. Determine the number of yeast cells per milliliter. The cell count should be roughly 1 X 108 cells/ml for a saturated c......阅读全文

DNA片段的琼脂糖凝胶电泳（agarose－gel－electrophoresis）
【原 理】琼脂糖凝胶电泳是重组DNA研究中常用的技术，可用于分离，鉴定和纯化DNA片段。不同大小、不同形状和不同构象的DNA分子在相同的电泳条件下（如凝胶浓度、电流、电压、缓冲液等），有不同的迁移率，所以可通过电泳使其分离。凝胶中的DNA可与荧光染料溴化乙锭（EB）结合，在紫外灯下可看到荧光条带，籍
质粒DNA的琼脂糖凝胶电泳（agarose－gel－electrophoresis）
带电荷的物质在电场中的趋向运动称为电泳。电泳的种类多，应用非常广泛，它已成为分子生物学技术中分离生物大分子的重要手段。琼脂糖凝胶电泳由于其操作简单、快速、灵敏等优点，已成为分离和鉴定核酸的常用方法。实验目的：掌握琼脂糖凝胶电泳的原理，学习琼脂糖凝胶电泳的操作。实验材料：质粒DNA、BAC、植物总DN
