Run the whole selection.

No aptamer bench, or a small-molecule target that's stalled elsewhere? Bring the target — we run the full SELEX in Prof. Juewen Liu's group and hand you a validated binder, Kd and all.

Why teams come to us

The hard targets, done properly.

No bench, no months

Standing up a SELEX pipeline for one target is months of setup and equipment you don't want to own.

Small molecules resist

Tiny, low-immunogenicity targets are exactly where standard selections stall — and where capture-SELEX in our lab specializes.

A number, not a maybe

You need a binder with a measured affinity you can build a sensor or assay on — not a list of sequences and hope.

How it works

From target to validated binder, in four steps.

01

Define the target

We agree on the target, the counter-targets it must ignore, and the buffer your final assay will run in.

02

We run SELEX

Full selection in the Liu lab — capture-SELEX for small molecules — with the counter-selections that build specificity in.

03

Software picks winners

Each round, our engine ranks candidates by real-buffer structure — so we converge in fewer rounds, not brute force.

04

Validate & deliver

We measure Kd, truncate to a minimal binder, and hand over a candidate ready to build on.

What you get

A binder you can build on.

Not a sequencing pool — a finished, characterized aptamer, with the evidence a partner or investor will ask for.

  • A validated aptamer against your target
  • Measured binding affinity (Kd) under your assay buffer
  • Specificity data against the counter-targets
  • A truncated, minimal, synthesis-ready sequence
  • Structure & characterization report — usage terms by agreement

Milestone-based. You pay on results.

Scoping call
Free

We assess whether the target is a good fit for aptamer selection — and tell you honestly if it isn't — before anyone commits.

Milestone-based: a deposit to start, and the main fee on delivering a binder that meets an agreed Kd threshold — so the risk is shared, not all yours.

Questions

The obvious ones.

What kinds of targets?

Our strength is small molecules and other hard cases via capture-SELEX — pesticides, toxins, drugs, metabolites. Ask us about proteins and cells; if it's not a fit, we'll say so.

Who owns the aptamer?

We work that out together up front — and in practice it rarely conflicts. The lab keeps the right to publish the science; you take the aptamer to use directly or build into a sensor or assay. Publication and product use sit side by side. Exact terms by agreement, under NDA.

What if the selection doesn't yield a binder?

That's what the milestone structure is for: the bulk of the fee is tied to hitting the agreed Kd, so you're protected on the downside.

Can we just license the software instead?

Yes — if you have your own bench, the same engine is available as a commercial license. Start on the home page.
