Documentation-first supply
University procurement runs on documents. Every shipment is backed by a complete quality package, so your institution can file, audit and reproduce.
Lot-specific CoA
A Certificate of Analysis accompanies every batch, stating the lot number, the characterisation methods used and the results. HPLC, MS and SDS-PAGE data are available on request.
Specialist manufacturing partners
Raw materials come from dedicated IVD antigen, antibody and reagent manufacturers — specialist producers, not open-market trading. Manufacturer certificates available on request.
Cold-chain logistics
Lyophilised proteins ship worldwide with appropriate temperature control and documentation; buffer and preservative lines ship at ambient temperature.
Research-use compliance
Clear RUO and IVD-development labelling. Documentation for customs and institutional procurement is prepared with every order.
Evaluation samples
Evaluation quantities for research groups who need to qualify a lot against their existing assay before committing to a larger order.
Technical support
Direct access to answer questions on purity, format, reconstitution, buffer compatibility and assay interference.

Who manufactures the material we ship
We are a supplier, not a manufacturer — and we would rather state that plainly than imply otherwise. Materials are produced by dedicated IVD antigen, antibody and reagent manufacturers operating their own quality systems. Our role is specification, sourcing and documentation: we match the material to your application and make sure the paperwork travels with it.
What we can provide
The manufacturer's certificates where they exist, the batch CoA for the lot shipped, and their safety documentation. Batch traceability is recorded on the Certificate of Analysis that ships with the lot.
What we cannot provide
Our own ISO or GMP certificates, batch-release data issued in our name, or regulatory filing packages. If your programme requires these, tell us at the first enquiry and we will say straight away whether we can serve it.
Why this is worth saying
A specialist supplier who is honest about the boundary is easier to work with than one who blurs it. If we cannot meet a requirement, you will hear it before you spend time on an evaluation.
Where each document comes from — and who stands behind it
"Quality documentation" is easy to promise and hard to trace. Here is the actual chain behind a shipment, step by step, including the parts we do not control.
1 — The production lot
The material is produced by a dedicated IVD antigen, antibody or reagent manufacturer, who assigns the lot number. That number is the anchor for everything downstream — if you quote it to us, we can locate the record.
2 — Characterisation
Purity and identity data are generated by the manufacturer for that lot, using methods such as SDS-PAGE, HPLC and mass spectrometry. These are the underlying data behind the figures on the certificate.
3 — The certificate
The CoA we ship states the lot number, the methods used and the results recorded for it. It describes the lot you actually receive — not a generic specification for the product line.
4 — Shipment and receiving
Cold-chain packing where required, with the commercial invoice, packing list and CoA. Your receiving record and our shipment record reference the same lot number, which is what makes an audit traceable rather than interpretive.
Two things we deliberately do not claim: we are not the manufacturer, and we do not issue batch-release data in our own name. What we control is the specification on the quotation, the lot number on the certificate, and the documentation set that travels with the shipment.
Quality questions we are asked
Is endotoxin tested on every lot?
Endotoxin is not a fixed catalogue value for most of our lines. Grades are available on request — the standard level, or a lower level where cell-based work is downstream — and the figure for the lot shipped to you is stated on its CoA. If your protocol requires a specific limit, state it at the enquiry stage so we quote against it rather than around it.
How is the certificate different from the manufacturer's own certificate?
The certificate you receive is issued against the lot shipped to you and carries its lot number. Where the manufacturer publishes their own specification sheet for a product line, we can share it as representative data — that is background on the product, while the CoA is the record of your specific lot. The published specifications page holds the representative sheets we are able to publish.
What happens if a lot arrives and the data does not match?
Tell us with the lot number and what you measured. Discrepancies are investigated against the manufacturer's record for that lot, and if the material does not match the certificate we do not ask you to absorb it. Reproducibility claims only mean something if they hold when something goes wrong.
