Codon optimization service

Online Inquiry

Codon optimization is a crucial technique used to strategically modify the genetic code of a gene in order to enhance protein expression in a specific host organism. By fine-tuning codon usage, we can significantly improve protein production yield, enhance protein functionality, and increase overall efficiency.

The main purpose of Codon optimization is to increase the expression level of recombinant proteins. In common expression hosts, the frequency of use of different codons varies, and lower frequency of use of certain codons may limit protein expression. By adjusting the codon sequence of recombinant genes, the expression efficiency of proteins in specific hosts can be improved, thereby increasing protein production.

Case Studies

Thirty native and codon-optimized (synthetic) human SDR genes were expressed in E. coli BL21(DE3)-R3, with an induction temperature of 18 o C, and their expression and solubility profiles were compared. All of the experiments mentioned were carried out independently in triplicate. Expression was scored by the visualization of a band of the correct size by SDS–PAGE. Presence of a protein band in the total cell lysate which is not seen in control cultures (E. coli cells bearing expression constructs for differently-sized proteins) is scored as ‘‘expression”; the recovery of soluble protein after Ni-affinity purification is referred to as ‘‘solubility”. Improved expression and/or solubility was identified as an increase in the intensity of the band or better consistency seen between the three experiments and is therefore not fully quantitative.

Fig. 1 shows the result of an experiment with three genes, DHRS4, HADH2 and HSD17B4, in which codon optimization had a significant impact on expression and, at least in the case of HSD17B4, on the recovery of soluble protein. (The recovery of soluble protein seen for DHRS4 corresponds to yields of 1–2 mg/L of culture, while that of HSD17B4 corresponds to >10 mg/L.)
