Description Lambda DNA/EcoRI+HindIII Marker is recommended for sizing of linear double-stranded large DNA fragments in agarose gels. Lambda DNA is digested to completion with the appropriate Fermentas PureExtreme® restriction enzyme(s), purified and dissolved in storage buffer. DNA fragments contain various sticky ends depending on the restriction enzyme used for preparation of the marker. Lambda DNA/EcoRI+HindIII Marker can be labeled radioactively with T4 Polynucleotide Kinase. Alternatively, it can be labeled radioactively or non-radioactively with Klenow Fragment or Klenow Fragment, exo- with the fill-in reaction, see protocols. Features Sizing and approximate quantification of large DNA fragments. Sharp bands. Supplied with loading dye for sample DNA. Quality Control Well-defined bands are formed during agarose gel electrophoresis. The DNA concentration is determined spectrophotometrically. The absence of nucleases is confirmed by a direct nuclease activity assay. Storage Buffer (TE buffer) 10 mM Tris-HCl (pH 7.6) and 1 mM EDTA. 6X DNA Loading Dye 10 mM Tris-HCl (pH 7.6), 0.03% bromophenol blue, 0.03% xylene cyanol FF, 60% glycerol and 60 mM EDTA. |
