Can one order poly dT and poly rA from IDT and if so, what different forms of purification are available?

IDT offers both poly dT and rA oligonucleotides. Poly dT oligos can be ordered with standard desalting, PAGE, HPLC, or RNase-free HPLC purification.
RNA oligos are more difficult to synthesize than DNA oligos.

Poly rA sequence longer than 15 nt must be reviewed by our synthesis group to determine whether the oligo can be synthesized.

Poly rAs can be ordered with standard desalting and RNase-free HPLC purification.
