- 1 kb DNA Step Ladder - Size range 250-10.000
bp.
|
- Description
|
- The 1 kb DNA ladder consists of 13 blunt-ended DNA fragments ranging
in size from 250 bp to 10 kb. The 1 kb and 3 kb bands are present at
an increased intensity to simplify size assigment. The marker can be
internal labeled by nick translation protocol or end-labeled using TdT
and T4 DNA polymerase or in phosphate exchange reaction using T4 PNK.
- The marker can be optimal separated and analyzed in a 0,8-1% agarose
gel stained with ethidium bromide. Load 0,5-1 µg per lane (5-10
µl of the ready-to-use marker). The 6xloading dye (40% Sucrose,
0,1% bromophenol blue, 0,1% xylene cyanol FF) supplied with this marker
is used for loading DNA samples into gel wells and tracking migration
during electrophoresis. The xylene cyanol migrates with bands of approximately
4 kb and bromophenol blue with bands of approximately 300 bp in 0,5-1,4%
agarose gels in 0,5xTBE.
