Scientific Foundation of Recombumin®

Albumin – Designed by Nature, Enhanced by Sartorius Albumedix

With close to four decades of experience working with albumin and its biology, we have only just begun to unlock the vast potential of this unique molecule and its exceptional biological relevance. The structure of albumin gives it excellent stability, making it resilient to environmental stress both outside and inside the body; click the image below to uncover some of the key properties of albumin, and to find out more visit the Albumedix scientific library.

Beyond Evolution. Recombumin®- Albumin Revolution by Design.

Nature, by evolution, has developed a versatile molecule, albumin, with unique characteristics and properties. Through revolutionary approaches, Sartorius-Albumedix has perfected what nature created to enable effective applications of albumin that support the development and commercialization of an array of life science products. These enhancements and the high levels of consistency Recombumin® offers overcomes the limitations that blood derived albumin can present.

Human Serum Albumin (HSA) prepared from plasma presents different genetic variants and exhibits varying degrees of N-terminal truncation, glycation, oxidation and aggregation due to the extracted albumins' extended residence time in the body. Also, albumin is a natural transporter and readily binds to ligands; in blood-derived albumins this intrinsic property however manifests as varied ligand profiles. Unlike HSA, recombinant human albumin (rAlb) products have a remarkably high and consistent quality profile.

Functional Benefits

Delivering Benefits Through a Balance of Biological, Chemical, and Physical Properties

During manufacturing, formulation and dosing, advanced therapies and biopharmaceuticals are exposed to stressful, non-natural environments/conditions that may have a detrimental effect on quality/safety, consistency and therapeutic effect.

Recombumin® is an effective and versatile stabilizer for protein, peptide, vaccine, and cell and gene therapy products. It has been proven to ensure a natural micro-environment from lab to arm, protecting biopharmaceuticals against aggregation, particle formation, surface adsorption, chemical degradation, and apoptosis.

Recombumin® Prevents Adsorption

Adsorption: Non-specific adsorption without Recombumin® vs. Recombumin® preventing non-specific adsorption.
  • Readily adsorbs to hydrophobic and hydrophilic surfaces
  • Forms a single monolayer
  • Prevents nonspecific adsorption

Recombumin® Prevents Aggregation

Aggregation: Aggregation without Recombumin® vs. Recombumin® preventing aggregation
  • Prevents aggregation
  • Disperses uniformly in a solution
  • Minimizes physical drug instability

Recombumin® Prevents Oxidation

Oxidation: Free radicals without Recombumin® vs. Recombumin® protecting against free radicals
  • Scavenges free radicals
  • Protects formulations against modification from oxidation stress

Recombumin® Applications

Explore the variety of applications that Recombumin® recombinant human albumins can support. 

In cell therapy, the source and quality of albumin has proven important for both performance and regulatory purposes. Recombumin® recombinant human albumin products are used in a range of cell therapy media and products offering high performance, consistency and extensive regulatory documentation. 

Gene therapies demand stability and utilise albumin to support multiple unit operations across the workflow. Recombumin® offers a high performing, consistent and regulatory supported alternate to serum albumins.

Prophylactic to therapeutic, traditional formulations to viral vector based and oncolytic, vaccines encompass a diverse range of products. Having been safely administered as part of a final vaccine formulation over 210 million times Recombumin® has proven its value to developers and producers by protecting from sheer stress, surface adsorption, and by providing thermal stability to sensitive vaccines.

Optimizing efficiency and performance of protein and peptides can be challenging. Recombumin® has a long history in the stabilization of proteins and peptides by preventing aggregation, surface adsorption and oxidation.

The biocompatibility of coatings is crucial when developing next generation medical devices to avoid to the risk of toxicity and immunological responses leading to device rejection. The natural properties of recombinant human albumins make them a fully biocompatible choice for medical device coatings. Recombumin® supports developers by offering a recombinant, human and animal origin free batch to batch consistent albumin raw material for medical device applications.
