What is Recombinant Human Serum Albumin?

Recombinant Human Serum Albumin (rHSA) is a non-animal-derived protein, produced using advanced cell culture techniques. It mimics native human albumin in structure and function and is ideal for a wide range of applications:

• Cell culture media supplementation
• Diagnostics & IVD manufacturing
• Biopharmaceutical formulation
• Regenerative medicine and tissue engineering
