Service Overview

Bridge the Gap Between Sequence and Expression

Our platform combines advanced AI algorithms with proven optimization strategies to maximize your protein expression in E. coli.

The Challenge

Native gene sequences often contain codons that are rarely used in E. coli, leading to translation stalls, misfolding, or poor expression yields. This mismatch between host and foreign codon usage is a primary bottleneck in recombinant protein production.

  • Translation stalls and ribosome queuing
  • Protein misfolding and aggregation
  • Low expression yields

The Solution

Our advanced codon optimization algorithm redesigns your gene sequence using synonymous codons preferred by E. coli without altering the encoded amino acid sequence, maximizing translational efficiency and protein yield.

  • AI-powered sequence redesign
  • Multi-parameter optimization
  • Up to 100× expression improvement

FAQ

Frequently Asked Questions

Find answers to common questions about our service.

What is codon optimization and why is it important?
Codon optimization is the process of redesigning a gene sequence using synonymous codons that are preferred by the expression host without changing the encoded amino acid sequence. Native genes often contain codons rarely used in E. coli, which can cause translation stalls, protein misfolding, and poor expression yields. By optimizing codon usage, we can significantly improve translational efficiency and protein production.
How does your AI-powered optimization work?
Our optimization platform uses deep learning models trained on thousands of high-expression E. coli genes. Unlike traditional frequency-based methods, our AI considers sequence context, mRNA secondary structure, codon pair usage, and 200+ other factors to predict optimal codon selections. This multi-parameter approach typically achieves better expression results than simple high-frequency codon replacement.
What expression improvements can I expect?
Expression improvements vary depending on the native sequence and target protein. While typical improvements range from 5-20×, our optimized sequences have demonstrated up to 100× improvement in challenging cases. The average improvement across all projects is approximately 15×. We provide detailed analysis reports showing the predicted CAI improvement and expression potential before you proceed with gene synthesis.
Can you protect specific regions of my sequence?
Yes, we can protect specific regions from optimization based on your requirements. This is useful when you need to preserve native regulatory elements, specific epitopes, or functional domains. Simply indicate the regions to protect during sequence submission, and our algorithm will maintain those sequences while optimizing the surrounding regions.
What E. coli strains do you support?
We support all common E. coli expression strains including K-12 derivatives, BL21 (DE3), Rosetta, Origami, and Shuffle strains. Different strains have different codon usage preferences, so we optimize specifically for your target strain. We also offer multi-strain comparison options to help you select the best host for your protein.
Do you avoid over-optimization?
Yes, our algorithm deliberately avoids over-optimization. Recent research has shown that excessive codon optimization can actually worsen protein yields due to increased metabolic burden and impaired folding kinetics. Our balanced approach maintains appropriate rare codon usage where beneficial for proper protein folding, preventing the pitfalls of over-optimized sequences.
