All bands in 250bp DNA Ladder are blunt end, which avoiding any artifacts caused by band reannealing.
The 250bp DNA Ladder consists of 8 DNA fragments ranging from 250bp to 4500bp(250, 500, 750, 1000, 1500, 2000, 3000, and 40000bp, the 1000bp fragment is 100ng, others are all 50ng).
The fragments may be stained with ethidium bromide and should be run on a 1% agarose gel for maximum visualization.
It is suitable for use as molecular weight standards for agarose gel electrophoresis.
Recommended Loading: 5μl.
Range (bp): 250–4500.
