Antigen & antibody matching support
The hard part of building an assay is rarely choosing the analyte. It is getting a capture and detection pair that behave together in your matrix. We are not a manufacturer — we are the technical sourcing partner who gets you a combination that fits, together with the paperwork your institution needs.
How a matching enquiry works
Tell us the assay format
Sandwich or competitive, the platform (ELISA, CLIA, lateral flow, turbidimetric), the sample matrix and the sensitivity you need. If you have a target value from the literature, send it.
We come back with options
We hold conversations with dedicated IVD antigen and antibody manufacturers, describe your format and return the combinations that plausibly fit — with the specification and the documentation each one carries.
You evaluate on your own bench
Evaluation quantities so you can run the pairing against your existing assay rather than trusting a data sheet from an unrelated matrix.
Lock the combination and the lot
Once a pair works, we record it against your institution and reserve the same lot for reorders, so the next shipment does not restart your validation.
What we can source
Matched pairs
We will ask our manufacturing partners whether a matched capture/detection pair exists for the format you describe — and we will tell you plainly if it does not. Where a pair does exist, you evaluate a combination rather than two unrelated reagents.
Antigen and calibrator materials
Recombinant proteins and purified antigens, including carrier-free formats where your calibrator matrix demands it.
Controls and blockers
Control materials and the buffer, blocker and preservative components that go around them.
Bulk and custom quantities
Scale-up quantities and custom packaging once a combination has been validated on your platform.
What we need from you
| Item | Why it changes the answer |
|---|---|
| Assay format and platform | Determines whether a pair is viable at all, before any specification question |
| Sample matrix | A pair that performs in buffer can fail in serum; the matrix is part of the specification |
| Required sensitivity | Sets the required affinity and the antibody concentration you will need to conjugate |
| Calibrator expectation | Decides whether carrier-free antigen is mandatory or merely preferable |
| Timeline and quantity | Determines whether we work from stock or against a production slot |
Being clear about what we are — and what we are not
We do not manufacture. We do not operate a GMP facility, we do not hold our own ISO certificates, and we do not issue batch-release data. Materials are manufactured by dedicated IVD antigen and antibody manufacturers with their own quality systems; we can request their certificates and batch documentation for the material offered to you.
If your programme requires GMP-grade material, a regulatory filing package or a manufacturer-signed quality agreement, say so in the first message — we will tell you plainly whether we can serve it, rather than discovering it three emails later.
What we stand behind instead: specification clarity, the document package, response time, and supply consistency on the lot you validated.
