    agarose gel concentration

    distinguished linear DNA fragment size (kb) 3, DNA molecule morphology: in the same concentration of agarose gel, ultra-helical DNA molecule migration rate is faster than linear DNA molecules, linear DNA molecules than open-loop DNA molecules.


    4, current strength: gel voltage per centimeter does not exceed 5V, if the voltage is too high resolution will be reduced, only at low voltage, linear DNA molecule electrophoresis migration rate is directly related to the voltage used.
