Cell Culture Media

When you're formulating serum-free or chemically defined media, every component matters. A single contaminated or out-of-specification lot can force reformulation, delay production, or compromise downstream results.

Athens proteins eliminate that risk. Our cell culture supplements are purified in-house with endotoxin control from the start.

What sets Athens apart for cell culture applications:

• Low-endotoxin manufacturing – our purification processes minimize endotoxin throughout. The result: consistently low EU/mg values you can build formulations around.
• Multiple grades for different needs – Tissue Culture (LEL) grades for research, BioProcessing grades for commercial manufacturing. Same protein, different specs.
• Lot-to-lot consistency – when you validate a formulation with Athens proteins, it stays validated. No surprises when you scale or reorder.
• Scalable supply – from gram-scale R&D work to kilogram-scale commercial production using proven purification methods and quality standards.

Transferrin, lipoproteins, catalase, superoxide dismutase, vitronectin, and other supplements are trusted by media manufacturers worldwide for serum-free and chemically defined formulations.
