Soluble Protein Expression service

Detai Biologics provide soluble protein expression service. It gets the protein that is close to the natural state. It is suitable for the low expression level of soluble protein and inclusion body or the protein can’t be folded properly.

Detai Biologics owns a self optimization platform for soluble protein expression which contains codon optimization, Selection of host bacteria, Optimization of expression conditions, soluble protein analysis, protein purification condition optimization, Guarante the solubility of protein.
