Custom & additional analytes
Our listed catalog is deliberately short — we only list material we can ship with the documentation that goes with it. The analytes below are supplied on request: they are sourced to order against your specification, so availability, grade and lead time are confirmed per enquiry rather than published as fixed catalogue lines.
We do not hold every item below in stock. State the analyte, quantity, target purity and your downstream application, and we will come back with availability, specification, lead time and a quotation — or say straight away if we cannot serve it.

Cannot find the analyte you need?
The list above is illustrative, not exhaustive. If your target is not shown — a less common biomarker, a specific antibody pair, a conjugated or custom-expressed protein — describe it and we will tell you whether we can source or custom-produce it.
How a to-order analyte enquiry proceeds
Custom sourcing works differently from catalog ordering, and it is worth knowing the shape of it before you write:
1 — You describe the target
Analyte, quantity, target purity and the downstream application. The application matters more here than anywhere else — it decides which of several available formats is actually suitable.
2 — We check, not promise
We confirm availability, grade and lead time with the manufacturers before replying. You receive facts from the specification sheet, not an optimistic first answer.
3 — A straight answer
You get availability, specification, lead time and a quotation — or a plain statement that we cannot serve the requirement. We will not hold a project hostage to a maybe.
4 — Documentation to match
Whatever we source ships with the same documentation discipline as the catalog lines: lot-specific CoA, purity data on request, and export documents matched to your country.
What moves price and lead time
| Factor | How it changes the quotation |
|---|---|
| Quantity | The strongest lever by far — an evaluation size and a production batch are priced from different stock positions entirely |
| Purity and endotoxin grade | Sub-0.1 EU/µg material requires additional process control and is quoted accordingly |
| Format | Carrier-free, tagged or lyophilised vs liquid — each is a different production path with its own lead time |
| Conjugation | Unconjugated material ships from existing stock far more often than a custom label |
| Destination | Shipping mode and document set are confirmed at quotation, not discovered at the border |
