1kb DNA ladder is suitable for sizing linear double-stranded DNA
fragments from **0 bp**0 kb, and composed of ten
chromatography-purified individual DNA fragments. All bands (except
2kb and 5kb) are supplied at approximately *0 ng/5μl. The 2kb and
5kb bands have increased intensity relative to the other bands on
an ethidium bromide-stained agarose gel.
