GRS Ladder 20bp

GRS DNA Ladder 20bp is a ready-to-use DNA Marker suitable for sizing linear double-stranded DNA fragments from 60bp-300bp, and composed of 13 linear chromatography-purified individual DNA fragments. All bands (except 100bp and 200bp) are supplied at approximately 40ng/5μl. The 100bp and 200bp bands have increased intensity for easy identification.
