Recombinant Human Serum Albumin

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.

Why Choose Our Recombinant HSA?

Traditionally, Human Serum Albumin is derived from human plasma, which can introduce variability and risk of contamination. Our recombinant HSA, produced in a controlled, animal-free system, delivers consistent, high-purity protein for critical applications.

Our HSA finds its application in among others cell culture and biopharmaceutical formulations, protein stabilizer and diagnostic assay development.

Recombinant Human Serum Albumin

Human Serum Albumin (HSA) is the most abundant plasma protein and plays a central role in ligand transport, osmotic pressure regulation and stabilization of biomolecules. The protein contains multiple binding sites for fatty acids, drugs and endogenous metabolites, making it widely used in biochemical and pharmaceutical applications.

Recombinant HSA expressed in defined systems such as our Hansenula polymorpha expression platforms provides a consistent and well-characterized protein source. In contrast to plasma-derived material, recombinant production ensures absence of human pathogens and batch-to-batch variability.

This supports reproducible formulation development, drug binding studies and analytical assay standardization.
