OriBio™ D2K Plus Wide Range DNA Ladder is recommended for sizing and approximate quantification of a wide range of linear double-stranded DNA fragments from 100 bp-5 kb. This ladder is an expanded version from our most popular D2K Wide Range DNA Ladder. It consists of 8 linear double-stranded DNA fragments, adding a 3 kb and a 5 kb fragments for broader range, and is premixed with 1× DNA loading dye for direct loading on agarose gel. The 750 bp fragment has increased intensity to serve as a reference band. The approximate mass of DNA in each of the bands is provided (base on a 5 µl/lane load) for estimation of sample DNA mass.

10 mM Tris-Cl (pH 8.4), 10 mM EDTA, 0.02% bromophenol blue, 5% glycerol.

Store at room temperature for 3 months, 4℃ for 1 year. For longer periods, store at -20℃. Avoid repeated freeze-thaw cycles.
