Ambion® RNA Century™ Markers are a set of 5 in vitro transcripts of 100, 200, 300, 400, and 500 bases. They are unlabeled for staining with EtBr and are provided in one tube containing 50 µg at a concentration of 1 mg/mL. They are premixed to give equivalent staining on a 5% polyacrylamide/8 M urea gel and are useful as RNA size standards in denaturing gel electrophoresis. 1–2 µg (2–4 µL) markers will generate 5 distinct bands on a TBE-Urea acrylamide gel with EtBr staining. Markers are also tested to be nuclease-free and stable overnight at 37°C.
For Research Use Only. Not for use in diagnostic procedures.
