Human Recombinant Holo Transferrin Cell Culture Animal Free Mammalian Cell Culture

ART202S Recombinant Holo Transferrin Animal Free Mammalian Cell Culture

Animal-Free, Pichia pastoris Expressed  For Mammalian Cell Culture

Iron delivery is a foundational requirement for mammalian cell growth and recombinant protein expression. Traditional plasma-derived transferrin carries inherent risks of blood-borne contaminants, batch-to-batch variability and regulatory hurdles, making it a bottleneck for serum-free media development and biopharmaceutical scale-up.

Anrate ART202S recombinant holo-transferrin is a high-purity, animal-free iron transport protein produced in a Pichia pastoris expression system. As a fully iron-saturated holo form, it delivers bioavailable iron directly to cells via transferrin receptors, serving as a safe, consistent and regulatory-friendly replacement for plasma-derived transferrin in serum-free and chemically defined cell culture workflows.

Key Advantages

I.100% Animal-Free, Zero Blood-Borne Risk

Expressed in recombinant Pichia pastoris with no animal-derived raw materials throughout the manufacturing process. Eliminates the risk of viral, mycoplasma and prion contamination, and supports compliance with FDA, EMA and ICH guidelines for biopharmaceutical development.

II.Pre-Saturated Holo Form, Ready to Use

Each transferrin molecule binds two ferric ions at full saturation. No additional iron chelation is required, simplifying media formulation and reducing process variables in mammalian cell culture.

III.High Purity & Ultra-Low Endotoxin

Purified via multi-step chromatography with ≥98% homogeneity. Endotoxin level is controlled below 0.5 EU/mg, minimizing cytotoxicity and inflammatory response, and ensuring compatibility with sensitive cell lines, stem cells and immune cell culture.

IV.Superior Batch-to-Batch Consistency

Standardized fermentation and purification processes guarantee stable protein concentration, iron saturation and bioactivity across production lots. Reliable batch consistency reduces experimental variation and supports reproducible biomanufacturing processes.

V.Broad Mammalian Cell Compatibility

Validated for use with CHO, HEK293, Vero, BHK, hybridoma, mesenchymal stem cells and iPSCs. Suitable for both basic research and industrial-scale bioproduction of antibodies, recombinant proteins and vaccines.

VI.Scalable Packaging, Global Supply

Available in 1 g, 10 g and 100 g pack sizes, with custom specifications on request. Stable production capacity and worldwide logistics support customers across North America, Europe and Asia-Pacific.
