General description

Sigma′s 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. In nucleic acid gel electrophoresis, five μl of the marker should be diluted in gel loading buffer and then loaded in a single lane on an agarose or polyacrylamide gel. Suitable for use in Northern and Southern blotting. All DNA markers can be stained with ethidium bromide, SYBR™ Green, and Nancy-520.

Application

1 kb DNA Ladder has been used as a molecular marker to determine the molecular weight and size of double stranded DNA during gel electrophoresis.[1]

Other Notes

For optimal resolution, the recommended agarose gel concentration is 0.75%.
Sigma′s 1kb Ladder is provided in a solution of 10 mM Tris-HCl (pH 8.0), with 1.0 mM EDTA.

  2. how to use this product. in what ratio we have to add dye in this.

    1 answer

    1. This product has been tested successfully at 2 µL, 5µL, and 7 µL., however for general use, a starting volume of 5 µL is recommended. Dilute 5 µL volume of D0428 with 25 µL of gel loading buffer. Product G2526 is used for testing purposes. For best results, a 0.75% gel is recommended.
