Recombinant Human Albumin HSA Cell Culture RHTF Transferrin CAR-T CAR-NK TIL Stem Cell Culture

Recombinant Human Serum Albumin (rHSA)   Research Grade Cell Culture Medium Supplement for Serum-Free Cell Culture Biomanufacturing

Beijing Anruite Biotechnology Co., Ltd. specializes in eco-friendly bio-manufacturing of medical-grade proteins, possessing world-leading industrialization technology for recombinant human serum albumin. Our product portfolio fully covers core cell culture demands of research institutions, stem cell pharmaceutical enterprises, and CGT (Cell and Gene Therapy) companies across the whole workflow from lab-scale R&D to commercial mass production, delivering safe, stable and scalable solutions for clients of all sizes and development stages.

I. Flagship Core Product: Recombinant Human Serum Albumin (ARTrHA)

A high-grade protein excipient tailor-made for immune cell and stem cell culture, an indispensable key component for serum-free, chemically defined cell culture systems, widely applicable to lab-scale trials, pilot scale-up and industrial mass production.

Product Specifications

• ART103S (Powder Form): Top recommended option with excellent solubility and superior batch-to-batch stability, ideal for large-batch culture medium preparation and long-term storage in industrial settings.
• ART103L (Liquid Form): Ready-to-use without reconstitution, simple operation that effectively cuts labor costs and contamination risks for research labs and small-to-medium production runs.

Product Advantages

1,Max Safety & Regulatory Compliance

Expressed in Pichia pastoris with zero animal-derived components throughout production, completely eliminating risks of blood-borne viruses, mycoplasma and prion contamination. Endotoxin level ≤0.5 EU/ml, fully compliant with GMP and global pharmaceutical regulatory standards, accelerating translational research and IND filing for pharmaceutical manufacturers.

2.Ultra-High Purity & Consistent Performance

Purity ≥99.0% (verified by SDS-PAGE), formulated with no extra additives or contaminating heteroproteins. It delivers reproducible stable results for laboratory research and uniform quality for industrial manufacturing.

3.Multi-Scenario Functional Compatibility

• Supports adherence and homogeneous proliferation of mesenchymal stem cells (MSCs), hematopoietic stem cells (HSCs), induced pluripotent stem cells (iPSCs), maintains stable cellular morphology and stemness, and preserves multipotent differentiation capacity.
• Markedly boosts expansion rate, viability and cytotoxic potency of CAR-T, CAR-NK, TIL and other immune cells, enabling efficient large-scale manufacturing of CGT products.
• Powerful antioxidant capability neutralizes harmful free radicals in culture media, slows cellular senescence, and greatly improves cell viability post cryopreservation and thawing.

4.Stable Large-Scale Supply

Supported by the world’s largest production facility with an annual output of 120 tons of recombinant human serum albumin, we are capable of fulfilling ultra-large batch orders. Our stable supply avoids extended delivery cycles and stock shortages commonly seen with imported products, reliably supporting long-term lab research for academic institutions and full-scale commercial manufacturing for pharmaceutical enterprises.

Supporting Recombinant Protein Portfolio

Anrate also supplies other high-purity recombinant proteins for full-process cell culture. Combined with recombinant human serum albumin, they enable complete serum-free culture systems:

Recombinant Human Transferrin (rHTF): Two variants available – apotransferrin (ART201S) and holotransferrin (ART202S). It chelates and transports iron ions, reduces reactive oxygen species, and delivers essential iron nutrients to support healthy cell growth. Purity exceeds 98.0% with hundred-kilogram-scale production capacity and reliable consistent supply.
