Albumin for cell culture, diagnostics and formulation
Bovine Serum Albumin (BSA) is one of the most widely used protein supplements in cell culture, diagnostics and biochemistry, valued for its stability, solubility and ability to bind and transport lipids, hormones and other small molecules. Different applications call for different specification grades — from general-purpose BSA through to Low Endotoxin, Fatty Acid-Free and pH 5.2 grades for more specific or sensitive use cases.
For applications requiring a human-derived or recombinant albumin rather than bovine — particularly cell therapy, ATMP manufacturing and other xeno-free workflows — we additionally supply Human Serum Albumin (HSA) and recombinant Human Serum Albumin (rHSA) across Premium, Economy and CHO-expressed grades.
Typical applications
- Cell culture media supplementation
- ELISA and immunoassay stabilisation/blocking
- Biopharmaceutical formulation and excipient use
- Enzyme stabilisation
- Lipid and hormone carrier studies
- ATMP and xeno-free cell therapy workflows (HSA/rHSA)
