Custom Synthesis

spec: From mg to kg scale

We run custom synthesis from milligram to kilogram scale. Send the target sequence, the purity you need and any modifications — acetylation, amidation, fluorescent labels, cyclisation — and we will confirm feasibility, timeline and price. Sequences up to 60 residues are routine for us, and most custom projects ship within the same 7–12 day window as catalogue items.
