1

Sequence

Written 5′ to 3′ · 15–60 bases (130 with UltraPAGE) · A, C, G, T and U

What happens to degenerate bases

Degenerate bases have no automatic price and go to a design request rather than being silently dropped, because a dropped base is a different molecule at the same price.

2

Synthesis scale

How much material comes back. More scale means more reactions out of one tube, not a better oligo — the purity specification is the same. The tiers on offer change with length: 2/5/10 OD across the board, plus 20 OD for 61–90 nt and 1 OD for 91–130 nt on UltraPAGE. Need a yield that isn't listed? Pick Other, say how much you need, and we price it by hand.

3

Modifications

None

A dye at the 5′ end and a quencher at the 3′ end make a hydrolysis probe, and the price switches to the flat probe price with both labels and HPLC included.

Every listed modification is priced live above as you pick it. Anything in a made to order group is something our manufacturer can make but does not publish a price for — pick it and the order becomes a quotation request rather than a priced line. Internal modifications are priced per site; tell us how many and we price it, and we confirm the exact positions with you before it goes into synthesis. A modification, an unusual position or more than one label per end that is not on these lists is made to order — send it as a design request and we come back with a price within one business day.

4

Backbone and sugar chemistry

None

Priced per site, not per oligo — which is how our manufacturer prices it too, so the arithmetic passes straight through. Adding either of these makes the oligo HPLC purified and the purification is already in the price.

5

Purification and what is in that price

6

How many tubes

The same sequence, more than once. A different sequence is a new line — add this one, then paste the next.

Ordering a whole plate? switch to the list — 96 and 384-well plates are priced per well, with no plate fee.
Not everything can be priced by a form, and we would rather say so than invent a number: RNA over 60 nt, more than one modification per end, oligo pools, plates with per-well normalisation, unusual chemistry. Configure it here anyway — the line goes into your order marked Quoted and we come back with a price and a design inside one business day. If you have no sequence yet at all, tell us what you are trying to do instead.
