This marker consists of 10 fragments between 100 bp and 1,000 bp in multiples of 100 bp and an additional fragment at 1,500 bp. The 500 bp band containing triple the mass of the other fragments, serves as a visible reference indicator; all other fragments appear with equal intensity on the gel. They are all double-stranded DNA fragments. Since this product is premixed with loading dyes and glycerol, it is possible to apply this product to agarose gel electrophoresis directly.
