Phosphorothioate Bond Linkage*
Phosphonoacetate (PACE) Linkage^

We highly encourage our customers to try the phosphonoacetate linkage! To correctly utilize this modification, the linkage needs to be on the 3’ side of a modified RNA base.

Example:

        

          
mX*mX*mX*AAACCCGGGUUU*mX*mX*mX

          
mX*mX*mX*AAACCCGGGUUUmX^mX^mX

If you have another modification that is not listed and we have already discussed it, then please use these wildcard notations and describe the modification in the description section. *case sensitive*
