9 DNA fragments: 0.5kb, 1 kb, 2kb, 3kb, 4kb, 5kb, 6kb, 8kb, and 10kb:
The DNA KB-Ladder includes 9 fragments ranging from 0.5-10.0 kilobases (KB). It is a mixture of several plasmids digested to completion with appropriate restriction enzymes.
The intensity of the 3.0kb band has been increased to yield an internal reference indicator. All other bands appear with equal intensity except the band at 0.5kb.
