Thermo Scientific RiboRuler Low Range RNA Ladder is a mixture of seven single-stranded RNA transcripts ranging from 100 to 1000 bp. They are chromatography-purified and produced from specific templates that contain a fragment of the pTZ19R polylinker and Lambda phage fragments, making them free from NTPs and RNA degradation products. The concentration of each RNA transcript is determined spectrophotometrically. To minimize the possibility of contamination during use, the ladder is aliquotted in smaller volumes.

Highlights:
• Sharp bands of uniform intensity
• Easy-to-remember band sizes and quantities (1000, 800, 600, 400, 300, 200and 100 bp)
• Approximate RNA quantification by predetermined concentration of ladder bands
• Supplied with 2X RNA Loading Dye

Applications:
• RNA sizing and quantification on native or denaturing gels
• Northern blotting
