Overview

GenScript provides convenient online instant quotation and ordering system to build your desired oligonucleotides for comprehensive applications. It is an integrated system to easily build almost all type of single-stranded oligos, such as DNA and RNA oligos with modification and labeling (dual and multiple labeling), antisense oligonucleotides (phosphorothioate DNA and RNA, 2'-OMe-RNA, 2'-F-RNA), chimeric oligonucleotides, etc.

To best use our online instant quotation and ordering system, please use GenScript defined codes as following:

1. Backbones

Phosphorothioated DNA A, C, G, T (A*), (C*), (G*), (T*)
RNA A, C, G, U (rA), (rC), (rG), (rU)
Phosphorothioated RNA A, C, G, U (rA*), (rC*), (rG*), (rU*)
2'-OMe-RNA A, C, G, U (mA), (mC), (mG), (mU)
