Agarose Gel Electrophoresis - an overview | ScienceDirect ...

Agarose gel electrophoresis can separate DNAs up to 20 kb in size, but larger DNAs cannot be separated or do not even enter the gel. Reducing the agarose concentration to 0.1% has allowed the separation of DNAs as large as 500 kb, but such low-percentage agarose gels are very fragile and extremely difficult to handle ( Anand, 1986 Chap. 5) .
