FAQs
What is rice-derived recombinant human serum albumin (rHSA)?
Rice-derived recombinant human serum albumin (rHSA) is a recombinant form of human albumin produced using a rice-based expression system. It provides an Animal-Origin-Free (AOF) alternative to plasma-derived human serum albumin.
What is the difference between rice-derived and yeast-derived rHSA?
Both products provide recombinant alternatives to plasma-derived human serum albumin. The main difference is their expression system. Rice-derived rHSA uses a plant-based production platform, while yeast-derived rHSA uses Pichia pastoris. Their quality specifications also differ.
Is Canvax rice-derived rHSA Animal-Origin-Free?
Yes. Canvax Rice-Derived Recombinant Human Serum Albumin is specified as Animal-Origin-Free (AOF) and uses a rice-based expression system.
What is the concentration of Canvax rice-derived rHSA?
Canvax rice-derived rHSA comes as a ready-to-use 20% liquid solution. The specified protein content is 20.0% ± 1.2%, and each vial contains 50 mL.
Can rice-derived recombinant human serum albumin be used for protein stabilization?
Yes. Rice-derived rHSA can serve as a stabilizing protein component in research formulations. Potential applications include vaccines, antibodies, viral vectors and other biological products. Users should evaluate performance for each specific formulation.
Is GMP-grade recombinant human serum albumin available from Canvax?
Canvax offers GMP-grade recombinant human serum albumin options for regulated biomanufacturing projects. Contact our team to discuss the available expression platforms, quality documentation and supply requirements.
How should rice-derived rHSA be stored?
Store Rice-Derived Recombinant Human Serum Albumin at 2–8 °C and avoid freezing. Canvax ships the product with gel packs.
Martin Castle –
I prefer working with liquid albumin preparations when testing different formulations, as they simplify the preparation of working solutions. This rHSA from rice comes at 200 mg/mL, which gives us flexibility when adjusting the final protein concentration. It is a convenient format for our routine laboratory experiments.
Emmanuel Garcia –
We selected this rice-derived recombinant human serum albumin for our protein formulation development work. Having a 20% ready-to-use solution makes it easier for us to prepare different albumin concentrations without an additional reconstitution step. The animal-origin-free composition is particularly relevant for our formulation studies, where we try to keep raw material sources well defined.
Francisco Gonzalez –
In our lab, we pay particular attention to the origin and specifications of proteins used in formulation experiments. This plant-derived human serum albumin is an interesting alternative when we want to avoid animal-derived materials. I also appreciate having product specifications available to review before incorporating a new reagent into our workflow.
