Description
GeneRuler High Range DNA Ladder, ready-to-use, is recommended for fast sizing and approximate quantification of high molecular weight double-stranded DNA fragments in agarose gels (in 1.5 hour, 0.4% agarose gel). The ladder is a mixture of chromatography-purified individual DNA fragments.
GeneRuler High Range DNA Ladder, ready-to-use, is premixed with 6X DNA Loading Dye for direct loading onto agarose or polyacrylamide gels.
The ladder is supplied with 6X DNA Loading Dye for sample DNA.
Features
Ideal for both DNA sizing and approximate quantification.
Ideal for fast sizing of high molecular weight DNA fragments
Sharp bands.
Ready-to-use ladders can be directly loaded and are stable at room temperature for 6 months.
Supplied with loading dye for sample DNA.
Quality Control
Well-defined bands are formed during agarose gel electrophoresis.
The absence of nucleases is confirmed by a direct nuclease activity assay.
