CRISPR Guides

crRNA, tracrRNA and non-targeting controls, chemically synthesised.

crRNA and its matched non-targeting control are chemically synthesised at a fixed 5 nmol scale, so they carry a catalogue price — send the target gene or the 20 nt spacer and add them to the order. tracrRNA is the same sequence for everyone and is quoted per batch. Full-length single-guide RNA and end-protected guides are made to order — send them as a design request and you get a figure and a lead time within one business day.

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.

Long RNA, unusual modifications, pools and plates are designed and quoted individually — free, within one business day. Send us the requirement.
