Animal-Free Manufacturing · Superior Batch Consistency · Global Regulatory Alignment

Product Overview

Serum-free and chemically defined cell culture media have become the industry standard for biopharmaceutical and CGT manufacturing. Transferrin, as a core functional component, plays an indispensable role in iron transport, cell proliferation regulation and antioxidant protection. Traditional plasma-derived transferrin presents inherent limitations in source variability, biosafety risks and batch-to-batch inconsistency, making it difficult to meet the compliance and stability requirements of industrial-scale production.

Manufactured via recombinant Pichia pastoris eukaryotic expression and purification with a fully animal-free production process, ART201S recombinant human apo transferrin eliminates blood-source related risks at the source. Presented in iron-free apo form with no bound iron ions, it is precisely compatible with iron-rich media formulations and supports the development and large-scale manufacturing of chemically defined culture media.

Key Product Advantages

1. Animal-Free Process for Global Regulatory Compliance

The fully non-human, animal-free recombinant expression process ensures clear source traceability and full manufacturing control. It fully aligns with global regulatory expectations for chemically defined media raw materials. Complete quality documentation is available to support customers in process submission and CMC dossier preparation.

2. Precision Apo Formulation for Flexible Media Development

The iron-free apo form carries no bound iron ions, enabling precise compatibility with inherently iron-containing media systems. It allows flexible adjustment of iron ion concentration in the system, avoids interference from excess iron on formulation stability, and optimally delivers iron transport, cell proliferation support and antioxidant functions.

3. Comprehensive QC System for Excellent Batch Consistency

A strict release testing standard is in place, with every batch tested for multiple critical indicators including appearance, pH, purity, protein content, iron residual and endotoxin. Controlled variation of key quality parameters across batches effectively reduces process validation costs and ensures stable, repeatable culture performance in large-scale production.

4. Multi-Specification Coverage for Full Lifecycle Scaling

Standard packaging options include 100mg, 1g, 10g and 100g, with customized packaging specifications available upon request. It covers dosage requirements across the entire lifecycle, from laboratory process development and pilot scale-up to commercial mass production.

Industrial Advantages of Lyophilized Powder Formulation

• Extended Shelf Life: Up to 5-year validity for unopened products when stored at 2~8°C in a light-proof, airtight condition, supporting large-volume long-term stocking and reducing inventory turnover and procurement management costs
• Flexible Reconstitution: Recommended to be reconstituted with sterile PBS or suitable solvents up to 50mg/mL, followed by sterile filtration. It can be diluted and aliquoted on demand to meet different formulation concentration requirements
• Robust Logistics: The powder form eliminates liquid leakage risks, and quality stability can be maintained with conventional temperature-controlled transportation, greatly reducing long-distance logistics losses and delivery risks
• Convenient Usage: Reconstituted sterile solution can be stored at 2~8°C for 30 days, adapting to the rhythm of multi-batch continuous production
