Can one order poly dT and poly rA from IDT and if so, what different forms of purification are available?
We offer both poly dT and rA oligos. Poly dT oligos can be ordered with standard desalting, PAGE, HPLC, or RNase free HPLC purification. Poly rA oligos are more difficult to make than dTs. Because of this, any poly rA sequence longer than 15nts in length would need to be reviewed by our synthesis group to determine whether the oligo can be synthesized. We offer standard desalting and RNase free HPLC purification for RNA oligos.
