Description GeneRuler 50 bp DNA Ladder is recommended for sizing and approximate quantification of a wide range of double-stranded DNA on agarose or polyacrylamide gels. The ladder is a mixture of chromatography-purified individual DNA fragments. GeneRuler 50 bp DNA Ladder can be labeled radioactively with T4 Polynucleotide Kinase, see protocol. The ladder is supplied with 6X DNA Loading Dye. Features Ideal for both DNA sizing and approximate quantification. Sharp bands. Bright reference bands (given in red). 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. 友情提示:本产品仅用于生命科学研究实验,不作为任何药物及其他用途。 |
