A flexible, individually customisable human serum partner
SeamlessBio supplies human serum, plasma, platelet lysate and autoimmune control sera collected from certified donor centres in the EU and the United States — fully documented and available without minimum order quantity.
Beyond our core product range, most parameters can be tailored to your specific protocol: donor age (including pre- or post-cycle donor profiles for female-donor-specific work, donors aged 18 and above as required by regulation), treatment (Heat Inactivated, Gamma Irradiated or Low Endotoxin on request), and packaging in either bottles or bags.
For applications requiring bovine-free, human-matched serum — particularly CAR-T and NK cell expansion, MSC manufacturing and other ATMP workflows — our FBS vs. Human Serum comparison explains the regulatory and immunological context in detail.
Typical applications
- CAR-T and NK cell expansion
- MSC and stem cell culture (xeno-free)
- ATMP and cell therapy manufacturing
- Diagnostic ELISA and lateral flow assay development
- Immunoassay controls and calibrators
- Autoimmune diagnostic kit validation
