Cell Therapy & ATMP Manufacturing: FBS, Human Serum, and hPL Supply
Advanced therapy medicinal products — CAR-T cells, iPSC-derived therapies, gene-modified cell products — place exceptionally high demands on cell culture reagents. Serum lots must be pre-screened and reserved months in advance, endotoxin levels must be minimal, and tetracycline-free grades are mandatory for inducible expression systems. SeamlessBio supplies specialty FBS grades, human serum, and human platelet lysate (hPL) for ATMP process development and manufacturing, with EU-origin supply chain and batch reservation available from research scale to GMP transition.
Key Reagents for Cell Therapy Applications
| Product | Grade / Specification | ATMP Relevance |
|---|---|---|
| FBS Tet-Free | Tetracycline <10 ng/mL | Mandatory for Tet-On/Tet-Off inducible CAR constructs and lentiviral packaging |
| FBS Ultra Low IgG | IgG <5 µg/mL | Eliminates bovine IgG interference in T cell activation and flow cytometry readouts |
| FBS Low Endotoxin | <1 EU/mL | Minimises innate immune activation in primary T cell and NK cell cultures |
| FBS ES Cell Pre-Tested | Pre-screened for pluripotency maintenance | iPSC culture, reprogramming efficiency maintenance, feeder-dependent protocols |
| FBS Heat Inactivated | 56°C / 30 min complement inactivation | T cell expansion protocols requiring complement-free serum |
| Human Serum AB | Type AB, complement-active or heat inactivated | T cell expansion medium supplementation; reduces xenogeneic background |
| Human Platelet Lysate (hPL) | Pooled, pathogen-screened | Xeno-free MSC and T cell expansion; GMP-transition preferred alternative to FBS |
Supply Requirements for ATMP Programmes
ATMP manufacturing has unique supply chain demands that differ from standard research use:
- Batch reservation: A single FBS lot must cover the entire manufacturing campaign — from process development through clinical batch production. SeamlessBio reserves dedicated lots for ATMP customers on request.
- Extended lot testing: Pre-screening panels for mycoplasma, sterility, bovine viral diarrhea virus (BVDV), and adventitious agents available through our supply partners.
- EU origin: EU-sourced FBS simplifies import documentation and reduces regulatory complexity for EMA ATMP submissions compared to US or Australian-origin material.
- Flexible packaging: Available from 100 mL research scale to bulk quantities for process development and GMP manufacturing.
From Research to GMP Transition
SeamlessBio supports ATMP customers at both research and pre-GMP stages. We work with process development teams to identify appropriate FBS grades early, reserve sufficient lot volume to bridge from research to first-in-human batch, and provide documentation packages aligned with EMA ATMP regulatory requirements.
