Agarose gel electrophoresis is a simple and highly effective method for separating, identifying, and purifying 0.5- to 25-kb DNA fragments. The Basic Protocol in this unit can be divided into three stages: (1) a gel is prepared with an agarose concentration appropriate for the size of DNA ...
Before casting an agarose gel, consult Table 2.1 to determine the appropriate percent agarose gel to use based on the size of DNA to be separated. Procedure 1. Determine the amount of agarose (grams) and volume needed. Use Tables 2.1 and 2.2 as a guide for agarose concentration and gel ...

Electrophoresis, Agar GelIndicators and ReagentsAn extensive series of experiments has been performed to study the mobility of DNA fragments ranging in size from 2.0 to 48.5 kilobose pairs. By varying the agarose concentration in the gels and the electric field strength, three DNA electrophoresis ...
and agarose concentration. Due to its high gel strength, SeaKem® Gold Agarose forms easy-to-handle gels at low concentrations (as low as 0.5%), which allow for the separation of larger DNA fragments by conventional electrophoresis as well as a decrease in the time needed to separate DNA ...
