8-Aza-7-deaza-A CEP
Notes: 8-Aza-7-deaza-a CEP features a nucleobase that is isosteric with adenine but offers a different pi-electron distribution. Description: The 2'-deoxyribonucleoside phosphoramidite 8-Aza-7-deaza-dA CEP, also known as PPA CEP, features a nucleobase that is isosteric with adenine but offers a different pi-electron distribution and thus an altered dipole moment, resulting in stronger stacking interactions in oligonucleotides.1 We now offer the ribonucleoside version, 8-Aza-7-deaza-A CEP (PPA Riboside CEP, BA 0267), a new compound, for use in the synthesis of altered RNA oligonucleotides. This product is from our Experimental Grab Bag. The compounds in this unique collection meet all of Berry & Associates' purity standards, but have not been proven in oligonucleotide synthesis. We hope that you may find them interesting and useful for your research. Use: 12 min coupling time, standard dilution, standard cleavage/deprotection. Download Product
