Use this order editor to order Chimeric Oligonucleotides, i.e., oligonucleotides that contain both ribo- and deoxyribo- nucleotides. To order are only sequences that contain only deoxyribonucleotides or ribonucleotides use the custom DNA or ssRNA order editors. The Chimeric ordering page should be used for ordering only mixed DNA/RNA sequences.

You can order the chimeric oligos either 1) manually or by 2) uploading an excel file after filling the details of the chimeric oligos.

Please use the following format to enter the various segments of the sequence:
ACGT = DNA bases,
(ACGU) = RNA bases,
A*C*(G*U) = PTO '*' linker between the DNA and RNA bases,
I = 2'-deoxyInosine,
U = 2'-deoxyUridine, and
standard IUB/IUPAC codes for the degenerate bases.

For example, to place an order for the chimeric dA dC rA rU dN rC dT dU dC*rC rU,enter the following AC(AU)N(C)TUC*(CU) in the chimeric order editor. Please note that all chimeric oligos are delivered after HPLC purification.
