SeamlessBio Human Serum Albumin 5% is an isotonic, sterile HSA solution for use as an ancillary material in cell therapy development and manufacturing. The 5% concentration matches the physiological plasma albumin concentration in human blood and is the preferred choice for washing and separation steps where an isotonic protein matrix is required.
Manufactured under ISO 13485-certified conditions, with full TSE/BSE freedom declaration and complete donor-to-batch traceability. Available in glass vials and single-use bags — on request.

The 5% concentration is the physiological standard for buffer solutions in cell therapy processing. It prevents non-specific cell adhesion to surfaces, reduces cell stress during mechanical process steps, and maintains a stable isotonic environment — without overloading cell cultures with excess protein.
| Application | Description |
|---|---|
| Cell Washing & Separation | Standard buffer additive for washing T cells, NK cells and HSC after activation, transduction or selection. Typical: 0.5–1% HSA final in PBS. |
| Density Gradient Separation | Protein additive in the dilution step before Ficoll/Lymphoprep centrifugation during PBMC isolation and leukopak processing. |
| Process Formulation & Transfer Buffers | Isotonic base solution for cell transfer suspensions and intermediate product buffers in ATMP manufacturing. |
| Cryopreservation (Dilution Step) | Carrier protein in the post-thaw dilution step to reduce DMSO content and stabilise cell viability. |
| Product | Concentration | Typical Application |
|---|---|---|
| HSA 5% Solution | 50 g/L | Cell washing, separation, transfer buffer |
| HSA 20% Solution | 200 g/L | Cryopreservation, ATMP final formulation |
| HSA 25% Solution | 250 g/L | ATMP final formulation, AAV stabilisation |

The 5% HSA solution is a sterile filtered preparation of Human Serum Albumin used primarily for clinical and laboratory applications. This solution contains 5% albumin derived from human plasma, ensuring high purity and safety. Human Serum Albumin plays a vital role in maintaining oncotic pressure and transporting important substances in the bloodstream. Due to its biocompatibility and physiological relevance, the 5% HSA solution is widely utilized in medical treatments for volume expansion, protein replacement, and as a carrier in pharmaceuticals.
The 5% HSA solution offers reliable therapeutic benefits, including restoring blood volume in patients suffering from trauma or surgery. Its sterile filtered process guarantees reduced risk of contamination and infection. Hospitals and clinics extensively use this albumin solution for managing shock, burns, hypoalbuminemia, and other conditions requiring plasma protein supplementation. Additionally, the solution’s purity and consistent concentration make it ideal for research and pharmaceutical formulations where precise protein content is critical.
Our 5% HSA solution complies with rigorous quality and safety standards. It undergoes stringent sterile filtration and testing to meet pharmacopeial requirements, ensuring it is free from pathogens and endotoxins. The manufacturing process adheres to Good Manufacturing Practices (GMP), providing healthcare professionals with a product that is reliable and safe for patient care. The 5% concentration is optimized for effective clinical use, balancing osmotic efficacy with patient tolerance and safety during treatment.
