Expression Optimization


Blue Heron Bio has developed a proprietary algorithm for protein expression optimization. Based on codon usage and comprehensive knowledge of optimal RNA structure for protein translation, Blue Heron can confidently deliver results in the desired organism.


  • Reliable – a proven algorithm: successfully used by many researchers ( Survey Result ).
  • Flexible – exclude unwanted restriction sites and special sequences, use a customer’s codon table, add flanking sequences.
  • Free – no charge for registered users
  • Easy to use


  • Login, or create a new account
  • Submit a protein sequence (when starting with a DNA sequence, please use our translation tool for conversion)
  • Select your model organism or your own codon table
  • Check any restriction sites to be avoided (optional)
  • Enter any special sequences to be avoided (optional)
  • Add flanking sequences (optional)
  • An optimized sequence will be emailed and posted on your secure account

Customer Example
Protocol: LGR4 and LGR6 proteins’ coding sequences were optimized using Blue Heron’s proprietary algorithm. Wild type and optimized sequences were cloned separately in pCMV-Entry vector. Each DNA was transiently transfected to HEK293T cells and incubated for 72 hrs. Proteins were purified using anti-DDK affinitive column and run on SDS PAGE, then stained with Coomassie Blue.
