DNA molecular weight markers and ladders

 is ideal for determining the size of double-stranded DNA from 250 to 10,000 base pairs

The 400 bp fragment is present at increased intensity to allow easy identification

The 500 bp fragment is present at increased intensity to allow easy identification

 ideal for determining the size of double-stranded DNA from 250 to 3000 base pairs

The DNA marker is useful for determining the size of double-stranded DNA ranging from 50 to 1500 bp. in agarose gel.

The DNA ladder consists of 14 DNA fragments: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1200, 1500, 2000 and 3000 bp. Fragments 500 and 1500 bp long. have a double concentration, which simplifies their identification in the gel.

The ladder is useful for determining the length of double-stranded DNA molecules in the range from 24 to 710 bp.
