Proteins
FEIYUEBIO establishes the protein expression systems from prokaryotic to eukaryotic with unique structures in vitro. This enables us to express transmembrane proteins, which are difficult to express.
FEIYUEBIO has the professional technical team, our advanced experimental apparatus can ensure each protein has the complete COA report and high quality. Through SDS-PAGE analysis, our purified proteins surpass 90% purity.
Benefit of Recombinant proteins
High biological activity
Confirm the biological activity of each protein in the appropriate biological system, ensure our strict QC activity parameters.
Lot-to-lot consistence
Maintain consistent manufacturing conditions, and test each new lot side-by-side with previous lots and master lots, in order to minimize lot-to-lot variability.
Custom protein capability
We also provide custom proteins from scratch protein development to customizing a protein.
Long-term stability
Our proteins are stable over long periods, since we monitor the bioactivity and physical state through multiple freeze/thaw cycles.
Comprehensive selection
Our protein catalog includes over 5,000 recombinant, active, native proteins spanning 35 species. In addition, we also provide more than 10,000 non-catalog proteins for different research areas.
Multiple expression system
Our multiple host expression system with different tags can satisfy various experimental requirements.
Expert support assistance
We manufacture all our proteins in-house, and maintain the complete control of protein quality.
Custom bottling options
Custom bottling options are available for special formulations or sizes.
