25/100 bp Mixed DNA Ladder is designed for determining the size of double stranded DNA from 25 to 2,000 bp. The ladder consists of 17 double stranded DNA fragments ranging in size from 25 to 200 bp in 25 bp increments, from 200 to 1,000 bp in 100 bp increments, and an additional fragment of 2,000 bp. The DNA marker fragments at 150, 500, 1,000 and 2,000 bp bands are two times brighter for easy identification.
