General description

Sigma′s Transcript RNA Marker (0.2 – 10 kb) contains 9 RNA transcripts from 200 – 10,000 bases. Two ul of the ladder should be diluted in gel loading buffer and then loaded in a single lane on an agarose gel.

Application

Suitable for size determination of small RNA using native or denaturing agarose gel electrophoresis.
Transcript RNA Markers 0.2-10 kb has been used as a molecular weight marker for northern blot hybridization.

Components

Sigma′s Transcript RNA Marker (0.2 – 10 kb) is provided in a gel-loading solution with 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

Other Notes

Contains nine defined RNA transcripts, 200–10,000 nucleotides
For optimal resolution, the recommended agarose gel concentration is 1.0%.
