20 bp-DNA-Ladder

Regular DNA ladder for the analysis of very small DNA fragments (left lane in figure).
The 100 bp fragment has been enhanced for easy analysis of the gel. All fragments are quantified, enabling quantitation of sample DNA in the gel. In order to avoid overlay of bands by bromophenol blue or xylene cyanol, Orange G was included as dye.

We recommend use of this ladder on the following special agaroses: High Resolution (Art. No. K297), HR-PLUS (Art. No. HP30), LM/PCR (Art. No. HP31), or an agarose with additional Synergel^™ (Art. No. 0184).
The 20 bp DNA-Ladder is highly compatible with the 100 bp DNA-Ladder equimolar (Art. No. T834). By combining both, a versatile ladder from 20 bp up to 1000 bp is obtained (right lane in figure).
