Recombinant proteins are proteins that are artificially synthesized by introducing the gene encoding a particular protein into a host organism, such as bacteria, yeast, or mammalian cells, which then produces the protein of interest. Recombinant proteins provide a consistent and reliable source of biological reagents, reducing variability between experiments and enhancing reproducibility. Their purity and homogeneity can be tightly controlled during production, ensuring high-quality results in downstream applications. They allows the production of large quantities of proteins that may be difficult or impractical to isolate from natural sources.
While recombinant proteins can be synthesized in-house, there are multiple benefits of outsourcing production:
- Faster time to results - concentrate on your core activities.
- Benefit from the expertise of the supplier - stringent QC.
- Wide choice of expression systems - E. coli, yeast, insect, mammalian
- Seamless upscale and transition to GMP - reproducible & consistent
We offer over 600'000 recombinant proteins from over 50 trusted suppliers.
