FAQ

• What makes GenXceed Cell-Free mRNA Template different from traditional plasmid-based DNA production?

  GenXceed utilizes Rolling Circle Amplification (RCA), a cell-free, enzymatic amplification process that eliminates the need for large-scale bacterial culture and plasmid extraction. This results in:

  • Higher purity – No bacterial host DNA contamination
  • Minimal endotoxin levels – Avoids endotoxin accumulation from bacterial fermentation
  • Faster turnaround – As fast as 3 business days, compared to 17-22 days for plasmid-based methods
• How does GenXceed ensure high purity and IVT compatibility?

  With our cell-free amplification process, there is no E. coli involved, eliminating the need for extensive purification steps and enabling us to deliver high-quality DNA with faster turnaround.

  We have shown that the final product consistently meets:

  • Endotoxin < 0.05 EU/μg and residual host DNA < 1% — to ensure cleaner IVT reactions
  • No RNase detected or added — protecting RNA integrity throughout the IVT process
  • Total protein < 0.5% — reducing the risk of enzyme inhibition or interference
• Can GenXceed support customized mRNA template designs?

  Absolutely. Our platform offers flexible design options, including:

  • Gene synthesis with your custom sequence of choice, with optional GenSmart™ codon optimization
  • Clone into: GenScript mRNA applied vectors (various poly(A) tail options), or your own custom mRNA vector
  • Final DNA templates meet the same high quality standards, Poly(A) guaranteed
