The Ambion® RNA 6000 Ladder is a set of six RNA transcripts with lengths of 0.2, 0.5, 1.0, 2.0, 4.0, and 6.0 kb. The 0.2 kb band is at a concentration of 20 ng/ μL (A260). The RNA 6000 Ladder is designed for use with Agilent's lab-on-a-chip. Three tubes containing 20 μL each are provided. 150 ng (1 μL) will generate 6 distinct bands when run on a RNA Labchip™ using the Total RNA or mRNA assay.
