• Low Endotoxin FBS: Contains less than 5 EU/mL (Endotoxin Units per milliliter)
• Very Low Endotoxin FBS: Contains less than 1 EU/mL

• Hybridoma cells for antibody production
• Primary immune cells (lymphocytes, T cells, B cells)
• Dendritic cells and macrophages
• Stem cells (MSCs, iPSCs) in regenerative medicine
• CHO, HEK293, and Vero cells for protein production
• Cell lines for AAV and viral vector production

For all cell lines that are sensitive to bacterial contamination or immune stimulators, Low Endotoxin FBS is the preferred choice.

• Store at -20°C for up to 10 years shelf life
• For maximum stability, store at -80°C (optional)
• Avoid direct sunlight and temperature fluctuations

• Use at 2-8°C in refrigerator for maximum 4 weeks
• Avoid repeated freezing and thawing (leads to protein denaturation)
• Thaw overnight at 2-8°C or in 37°C water bath (with constant swirling)

Documentation for GMP compliance:

• Certificate of Analysis (COA) – detailed quality testing of each lot
• Certificate of Origin (COO) – proof of origin
• MSDS (Material Safety Data Sheet)
• TSE/BSE compliance according to EU and FDA guidelines
• Viral safety according to 9 CFR (Code of Federal Regulations)

All lots are fully traceable and delivered with complete documentation.

Additionally, each lot is tested for its growth promotion on relevant cell lines.

All lots are tested for viral safety according to EU Regulation 999/2001 and FDA 9 CFR.

• Sterile Filtration (0.1 µm): Standard option, preserves all growth factors
• Heat-inactivated (56°C, 30 min): Inactivates complement factors, ideal for immunological assays
• Gamma-irradiated: Additional security for GMP production, reduces viral contamination

Recommendation: For most cell culture applications, sterile filtration is sufficient. We only recommend heat inactivation for specific requirements, as some growth factors may be lost in the process.

• 50 mL – ideal for initial testing and small experiments
• 100 mL – standard size for routine laboratory applications
• 500 mL – optimal size for regular cell culture work
• Bulk volumes (5 L, 10 L, 20 L) – for industrial production and bioprocessing

• Endotoxin level (Low vs. Very Low)
• Treatment (sterile filtration, heat-inactivated, gamma-irradiated)
• Packaging size
• Order quantity
