RiboRuler™ High Range RNA Ladder, ready-to-use
Ready-to-use RNA Ladder composed of 8 chromatography purified single-stranded RNA transcripts for RNA sizing and quantification on native or denaturing gels.
Detailní popis
RiboRuler High Range RNA Ladder 200 to 6000 bases, ready-to-use is a mixture of 8 chromatography purified single-stranded RNA transcripts (200 to 6000 bp long), produced from specific templates that contain a fragment of the pTZ19R polylinker and Lambda phage fragments. Ladder is premixed with loading dye.
Thermo Scientific RiboRuler High Range RNA Ladder, ready-to-use, is composed of chromatography-purified transcripts that makes them free from NTPs and RNA degradation products. The concentration of each RNA transcript is determined spectrophotometrically (see photo for precise quantities). To minimize the possibility of contamination during the use, the ladder is aliquotted in smaller volumes.
