The Supercoiled DNA Ladder contains fragments from 2 kb to 10 kb at 1-kb increments and an additional band at 12 kb. Each supercoiled band is at a known concentration, with the 7-kb band at a higher concentration than the others. The resulting brighter band in the middle of the ladder acts as a useful reference point.
Accurate size determination facilitated by evenly spaced bands
Fragments are exact multiples of 1000 bp
Includes useful reference point for determining location
More economical than comparable markers
10 fragments ranging in size from 2 kb to 12 kb
