Glen Research CE (ß-cyanoethyl) Phosphoramidites for RNA synthesis are produced and packaged to ensure the highest performance on commercial synthesizers.  Every batch is accompanied by a Certificate of Analysis and an HPLC trace, showing the results of our QC testing.  RNA Phosphoramidites are synthesis-tested with a minimum coupling efficiency of 97%.  Glen Research RNA monomers are packaged in industry standard vials which are specially cleaned to eliminate particulate contamination.  These monomers are available in a variety of packs, including high throughput (HT) and low cost (LC).  An UltraMild set is also available for situations where sensitive bases are in use.  Dmf-G (10-3029) has been discontinued and may be substituted with Ac-G (10-3025).
