Extraction of plasmid DNA from Escherichia coli (alkaline lysis)
The basic principle of plasmid DNA extraction by alkaline lysis is that solution I suspends the cells and EDTA can chelate with Ca2+ and Mg2+ to inhibit the act
Chromosome CBG specimen preparation experiment
Heterochromatin is condensed throughout interphase and metaphase and is therefore relatively constant in size. They are usually located near the mitotic grains
M13 Experiments on the preparation of phage-derived vectors
M13 phage is a filamentous phage that does not lyse bacterial cells after infection, but only utilizes intracellular material to complete its own proliferation,
