protein expression timeline

ArcticExpress 11℃ Expression, Overcoming Protein Misfolding and Insolubility

Low Growth Temperatures Significantly Enhance Protein Folding and Solubility

Figure 1. X-21p expression at both 11°C and 30°C. Solubility of X-21p was enhanced at the lower growth temperature in all cells expressing chaperonin Cpn60 and co-chaperonin Cpn10.

Improved Protein Activity with Cold-Adapted Expression Technology

Figure 2. ArcticExpress Cells (11°C) and BL21-Gold Competent Cells (37°C) were used to express phosphatase proteins PTEN and MTMR7 with GST epitope tags. Phosphatase activity was enhanced in proteins expressed in ArcticExpress system at 11°C.

pLte Plasmid Designed for High-level Expression of Soluble Protein


  1. Carrying cspA low-tep promoter, 11℃ induction, increasing the protein solubility;
  2. SD sequence inside, increase initiation codon efficiency;
  3. Forming TEE sequence, enhance the DNA transcription, thus boost the protein expression;
  4. AMP resistance screening.

pSUMO Plasmid Designed for Correct 3D Folding


  1. Carrying cspA low-tep promoter, 11℃ induction, increasing the protein solubility;
  2. With SUMO fusion protein, forming 3-D structure, promoting protein folding accuracy.
  3. SUMO enzyme precisely slicing fusion protein, no residues in N-terminal;
  4. Kan resistance screening.

  1. Protein analysis and project proposal is utmost welcome and totally free.
  2. To increase the expression level of your protein, codon optimization using our proprietary, NovoGene™ technology, is recommended to be performed during gene synthesis.
  3. Insoluble proteins maybe subject to protein refolding procedures.
  4. In all cases, final protein will be guaranteed to meet listed specifications, failing which, any charge to the customer will be waived (exclusions are applicable to membrane proteins, toxic proteins and for target proteins greater than 100kDa).
