The 50 bp DNA ladder is a mixture of specially designed double-stranded DNA fragments for determining the exact size of PCR products and engineered DNA fragments. The 50bp DNA
ladder consists of 17 DNA fragments ranging in size from 50 to 1500bp. The amounts of 200, 500 and 1200bp fragments are adjusted so that their increased intensities serve as easy references after gel electrophoresis. The ladders are supplied pre-mixed with loading
buffer(Containing Orange G as tracking dye).
