TrackIt™ 100 bp DNA Ladder is pre-mixed with sample buffer for ready-to-load convenience and room temperature storage. It consists of 15 blunt-ended fragments at 100 bp increments and is suitable for sizing double-stranded DNA from 100 to 1,500 bp.   MoreThere is an additional fragment at 2,072 bp. This ladder can be stained with SYBR® Safe, ethidium bromide and other nucleic acid stains or radiolabeled using T4 polynucleotide kinase or T4 DNA polymerase. For easy reference on agarose gels, the 600- bp band is two- to three-times brighter than the other bands in the ladder
