General description

Sigma′s DirectLoad™ 1 kb Ladder contains 11 fragments consisting of 500 bp repeats from 0.5 to 3 kb, 1 kb repeats from 3 to 6 kb, and 2 kb repeats from 6 to 10 kb. For NA electrophoresis, 5 ul of the marker can be loaded directly into a single lane on an agarose or polyacrylamide gel. Suitable for use in Northern and Southern blotting.

Application

Suitable for size determination of dsDNA by DNA electrophoresis with either agarose or polyacrylamide gels.

Features and Benefits

  • Ready-to-load
  • Easy-to-use
  • Popular band sizes

Components

Sigma′s DirectLoad™ 1kb Ladder is provided in a gel-loading solution of 2.5% Ficoll (Type 400), 0.0125% bromophenol blue, and 0.00625% xylene cyanol.

Other Notes

Contains 11 fragments consisting of 500 bp repeats from 0.5 to 3 kb, 1 kb repeats from 3 to 6 kb and 2 kb repeats from 6 to 10 kb.
For optimal resolution, the recommended agarose gel concentration is 0.75%.
