This marker consists of 9 fragments (100, 250, 500, 750, 1,000, 1,500, 2,000, 3,000, and 5,000 bp). The 1,000 bp fragment is brighter than the other fragments and serves as a visible reference indicator. 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 gel electrophoresis directly
