Humanes Serumalbumin (HSA)
Human Serum Albumin (HSA) — the most abundant protein in human blood plasma — in four application grades, multiple concentrations and two packaging formats. From research-grade cell culture supplement to pharmaceutical excipient grade for ATMP and vaccine formulation. All products on request — contact us for availability, documentation and pricing.
HSA by Grade
Human Serum Albumin is not a single product — it is a category spanning four grades with different quality systems, regulatory status and documentation packages. Choosing the wrong grade introduces regulatory risk. See our HSA vs. rHSA Grade Comparison for a complete guide.
HSA in Arzneimittelqualität
Plasma-derived HSA for use as an inactive ingredient (excipient) in pharmaceutical and biopharmaceutical formulations. Meets pharmacopoeial requirements (Ph. Eur./USP). Standard grade for vaccine formulation, stabilisation of therapeutic proteins and drug delivery applications.
- Plasma-derived from human donors
- Pharmacopoeial (Ph. Eur./USP) compliant
- Viral inactivation step included
- For use in pharmaceutical products
- Requires customer qualification and appropriate licensure
HSA, diagnostische Qualität
High-purity HSA specifically processed for use in IVD diagnostic applications — calibrator and control manufacturing, quality control products and immunoassay reagent stabilisation. Exceptional purity and lot-to-lot consistency for diagnostic test kit development and production.
- Exceptional purity — minimal interfering proteins
- Defined lot-to-lot consistency
- Suitable for calibrator and control manufacturing
- IVDR documentation available
- Batch reservation for IVD product lifecycles
HSA, für Zellkulturen geeignet
Human-derived albumin for xeno-free cell culture supplementation, ATMP manufacturing and cryopreservation. Eliminates xenogenic bovine albumin (BSA) exposure for human cell lines where xeno-free compliance is required. Standard for CAR-T cell wash buffers, MSC expansion and iPSC serum-free formulations.
- Human-derived — no bovine origin
- Xeno-free cell culture compliance
- Cell therapy and ATMP manufacturing
- Cryopreservation buffer supplement
- ISO 13485 or Near-GMP quality system
HSA Forschungsqualität
Cost-effective human albumin for research and development applications where pharmaceutical-grade documentation is not required. Serum-free media development, assay buffer formulation, blocking reagent and basic research applications. CoA per lot included.
- Research and development use
- CoA per lot
- Cost-effective for high-volume R&D
- Assay buffer and blocking applications
- Available from shop or on request
HSA Liquid Solutions
Pre-formulated HSA solutions in isotonic or concentrated formats — ready-to-use for cell culture washing, cell therapy processing and biopharmaceutical formulation.
HSA 5% Solution (50 g/L)
Isotonic — equivalent to physiological plasma albumin concentration. Standard for cell washing, separation buffers and isotonic cell therapy formulations. Available in PET/PETG vials and single-use bags.
HSA 20% Solution (200 g/L)
Concentrated solution — used where volume minimisation is critical. Final product formulation for cell therapy infusion preparations, where dilution to physiological concentration occurs at the point of use. PET/PETG vials and single-use bags.
HSA 25% Solution (250 g/L)
Hyper-concentrated solution for cryopreservation formulations, albumin spiking in defined cell culture media and volume-critical formulation development. Requires dilution for most cell culture applications.
Packaging Formats
Lyophilised Powder
Powder form for maximum stability and shelf life at ambient storage. Reconstitute to required concentration. Standard format for research and diagnostic grade HSA.
