Anrate ART201S Apo-Transferrin  Biomanufacturing Supplement

Animal-Free High Batch Consistency GMP-Aligned Raw Material for Serum-Free Cell Culture Media Production

Product Overview

Engineered for biopharmaceutical manufacturers, CGT enterprises and industrial-scale cell culture operations, Anrate ART201S is a premium recombinant human apo-transferrin expressed and purified from Pichia pastoris. As a critical serum-free medium supplement, it delivers reliable iron transport and cell proliferation support, eliminating animal-derived risks and batch-to-batch variations associated with plasma-sourced transferrin, to stabilize your large-scale production processes and accelerate regulatory compliance.

Core Industrial Advantages

I.Animal-Free Recombinant Expression, Zero Blood-Borne Risk

Produced via advanced recombinant DNA technology with a yeast expression system, ART201S is completely free of animal-derived components and human plasma impurities. It eliminates the risk of viral contamination and adventitious agents, fully aligns with regulatory requirements for biopharmaceutical raw materials, and simplifies your process validation and declaration work.

II.Ultra-High Batch Consistency for Scale-Up Production

Supported by a ton-level industrial production line and standardized purification processes, ART201S maintains strict quality consistency across batches. With purity ≥98% (HPLC) and tightly controlled iron content (≤0.005%), it minimizes process fluctuations in large-volume cell culture, ensures stable cell growth performance, and reduces production verification costs for long-term supply.

III.High Purity  Low Host Cell Impurities

With host cell protein (HCP) controlled at ≤100 ng/mg and low endotoxin levels, ART201S reduces interference with cell metabolism and downstream purification processes. It is suitable for high-density cell culture, antibody production, vaccine manufacturing and other demanding industrial scenarios, effectively improving product yield and process robustness.

IV.Stable Mass Supply & Customized Industrial Solutions

Backed by large-scale production capacity, Anrate provides stable long-term supply for bulk orders, with specifications covering 1g, 10g and customized bulk packaging. We offer tailored technical support for medium formulation optimization, process compatibility testing and exclusive account services for key accounts, to fully match your industrial production rhythm.

Key Industrial Applications

• Serum-free / chemically defined cell culture medium manufacturing
• Monoclonal antibody and recombinant protein bioproduction
• Cell & gene therapy (CGT) industrial-scale cell culture
• Vaccine production and biopharmaceutical excipient development
• Bioprocess scale-up and GMP-grade raw material substitution

Technical Specifications

How should I reconstitute recombinant apo transferrin lyophilized powder?

A: It is recommended to prepare the reconstituted solution at a concentration no higher than 50 mg/mL. Dissolve the lyophilized powder by adding sterile PBS solution or other suitable solvents, then filter the solution through a sterile filter membrane. You can further dilute the stock solution with other compatible solvents and aliquot it into working portions according to your usage requirements. The sterile reconstituted solution remains stable for 30 days when stored at 2–8 °C. Once opened, use the product promptly to avoid microbial contamination.
