AccuLadder 1Kb DNA size marker was designed for determining the size of double stranded DNA ranging between 500 to 10,200 bp. Acculadder is sharper and brighter than our standard 1Kb ladder. The Acculadder 1 kb DNA size marker consists of DNA fragments 0.5, 1.0, 1.6, 2.0, 3 (2.961), 4, 5 (5.007), 6 (5.991), 8 and 10 (10.2) kb. The 2.961 kb band is approximately two times brighter for easy identification.
