Century Marker Templates

The Century™ Marker Templates contain mixtures of linearized plasmids ready for use as templates in in vitro transcription reactions for synthesis of labeled RNA molecular size standards. When transcribed with T7 RNA polymerase, Century™ Marker Templates produce 5 RNA transcripts of 100, 200, 300, 400, and 500 bases. Century™-Plus Marker Templates produce 7 RNA transcripts of 100, 200, 300, 400, 500, 750, and 1,000 bases.
