If you are sourcing human serum in Europe — for cell culture, ATMP manufacturing, IVD development, or DMPK assays — you need a supplier who can deliver EU-origin material, full donor documentation, and flexible lot reservation without a 6-week lead time. This page explains what to look for and where SeamlessBio fits.
Looking to buy? See our human serum overview – all grades (mixed donors, Type AB, off-the-clot, male-only), EU stock, lot reservation up to 36 months.
What to look for in a European human serum supplier
| Criterion | Why it matters |
|---|---|
| Donor origin | EU and US donor centers have established screening frameworks (HBsAg, HCV, HIV-1/2, syphilis, NAT). Non-EU origin requires additional import documentation and may complicate regulatory submissions under EU IVDR or ATMP guidelines. |
| Lot documentation | Full CoA (sterility, mycoplasma, endotoxin, haemoglobin, total protein, IgG), donor screening results, and traceability to individual donation — required for GMP, ATMP CTA, and IVD submissions. |
| Lot reservation | Studies lasting 6–24 months require the same serum lot throughout. A supplier that cannot hold your lot will force mid-study lot changes — requiring re-validation. |
| Variant availability | Standard, Type AB, AB Male, Off-the-Clot, Heat Inactivated, Delipidated, Disease State — most applications need a specific variant, not just "human serum". |
| Stock in Europe | US-based suppliers shipping to the EU add 5–15 days transit, customs clearance costs, and cold chain risk. EU/Swiss stock ships in 1–3 business days, no customs delays for DACH customers. |
| Response time | For B2B enquiries, a quote within 24–48 hours is the standard. Longer indicates a distributor with no direct supplier access. |
