From DNA to Purified Protein - Our Workflow


  1. Sequence Design: To address issues related to codon usage bias, we offer codon optimization services, improving protein expression.

  2. Gene Synthesis and Plasmid Cloning: We synthesize DNA and clone it into a high-copy plasmid.

  3. Protein Expression and Optimization: We determine gene expression levels, analyze products, and offer scale-up.

  4. Protein Purification: Utilizing affinity chromatography, ion exchange, and gel filtration, we purify and characterize proteins.


     Optional Services:

    •  TAG removal   

  •  Endotoxin elimination   

  •  Scale-up fermentation and purification




     Get started: Contact us at protein@genosphere-biotech.com with:

         • Your gene or protein sequence or UniProt accession number.
         • Your preferred expression system(s).
         • The mg amount of
recombinant protein needed (0.1 mg, 0.5 mg, 1 mg...).
         • The purity level required (>80%; >90%).

     Five Expression Systems: Choose from bacteria, yeast, insect cells, mammalian cells, or in vitro expression.

     Affinity Tags: Customize with N-/C-terminal tags (e.g., GST, His6, His10, etc.).
