All bands in 200bp DNA Ladder are blunt end, which avoiding any artifacts caused by band reannealing.
The 200bp DNA Ladder consists of 8 DNA fragments ranging from 200bp to 4000bp(200, 400, 600, 800, 1000, 1400, 2000 and 4000bp, the 1000bp fragment is 100ng, others are all 50ng).
The fragments may be stained with ethidium bromide and should be run on a 2% agarose gel for maximum visualization.
It is suitable for use as molecular weight standards for agarose gel electrophoresis.
10mM Tris-HCl (pH 7.5), 1mM EDTA.
Store at –20°C.
