Recombinant Human Serum Albumin (rHSA) from Yeast Expression
Human Serum Albumin (HSA) is the most abundant protein in human plasma, essential for maintaining osmotic pressure and transporting key molecules. Through recombinant protein production, we offer a safer, animal-free alternative: recombinant HSA (rHSA), produced in genetically engineered Hansenula polymorpha yeast.
High-Purity, Animal-Free rHSA
Our rHSA is produced through a yeast-based recombinant protein expression platform. The HSA gene is inserted into the genome of Hansenula polymorpha, enabling the yeast’s endogenous protein machinery to produce tag-free rHSA.
The developed production process includes optimized upstream process development (gene integration, fermentation) and downstream purification (filtration, chromatography), resulting in high-purity rHSA (>95%).

Benefits of rHSA from Hansenula polymorpha
- Animal-free and free from viral contamination
- 95% purity verified by SDS-PAGE and HPLC
- Lyophilized powder for long-term stability and storage
- Ready-to-use: reconstitution requires no dialysis
- Manufactured in an EU-GMP facility
- Batch-to-batch consistency
Our Tag-free HSA is chemically and functionally identical to the plasma-derived HSA.
Applications
Our recombinant human serum albumin (rHSA) is highly versatile and widely used in research and biomanufacturing. As an animal-free, high-purity alternative to plasma-derived albumin, it supports both ethical sourcing and regulatory compliance in advanced biotech workflows.
Supplementation of cell culture media
Protein stabilizer in ELISA and Western Blot assays
Excipient in formulation and drug delivery studies
Use in vaccine development and diagnostic platforms
