In recent years, there has been an increased demand for animal-free components to replace serum or animal originated supplements to eliminate the risk of viruses and mycoplasma contaminants. Using the rice endosperm specific expression platform, the OsrHSA Advanced, which is animal component free, can provide an economical and safe approach for the production of non–animal-derived compounds.
Human plasma is also in limited supply. Rice as bioreactor show great promise as a flexible system for the production and processing of OsrHSA Advanced with intact biochemical features on a large scale. The rice endosperm specific expression platform is easy to be large-scale, because the rice endosperm has the protein body, which can keeps proteins stability and bioactivity. At present, the production capacity of OsrHSA is almost tons a year.
The OsrHSA Advanced is animal component free and has very good batch consistency, which has many advantages. These include:
01/ elimination or reduction of the potential risk of viruses and mycoplasma contaminants in blood derived products;
02/ void the impact of serum components in the experimental study;
03/ well-defined component;
04/ simplify the downstream bio-processing or biological research;
05/ stable supply and no dependence on a process based on fractionation from precious donated blood;
06/ very good batch consistency and avoid the batch difference.
