Electrostatic Electrophoresis Electron Microscope Technique for Nucleic Acid

This paper presents a new technique for nucleic acid electron microscopy, i.e, a technique using electrostatic field to cause electrophoretic motion. With water as mediam, the negatively charged nucleic acid molecules will move along the direction of an electrostatic field of electrode distance 12mm and voltage IKV. After under the action of this static field for 5 minutes, on the surface of drop, appear natural distributions of two dimensional structure of linear or ring shape. Compared with the routine technique of nucleic acid spreading, the above method is easier to work with, capable of saving more labor and time, ane economizing on reagents. These effects will make the user feel quite satisfactory.
