The sequence for a given miRBase ID does not change, so ordering one is a matter of naming it rather than designing it. Everything here is made to order — we do not hold stock — and the lead time is the same as any other synthesis. Order a mimic or an inhibitor and the matched control is the obvious thing to add; a silencing result without its control is not a result.
There is no price list to read here. Configure any item in this family in the order builder — sequence, yield, purification and modifications — and the price appears as you go, with the full breakdown, before anything is added to an order.
