Century™-Plus RNA Markers

Ambion™ RNA Century™-Plus Markers are a set of 7 in vitro transcripts of 100, 200, 300, 400, 500, 750, and 1000 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 7 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.
