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 8 business days, compared to 17-22 days for plasmid-based methods
• How does GenXceed™ ensure high purity and IVT compatibility?

  GenXceed™ templates undergo rigorous multi-step purification and quality control, ensuring:

  • Endotoxin levels <0.05 EU/µg – Minimizing immune response risks in downstream applications
  • No host DNA carryover – Eliminating bacterial genome contamination
  • Pre-validated IVT compatibility – Delivering high-yield, clean transcription
• How does GenXceed™ linear DNA compare to traditional linearized plasmid DNA?

  GenXceed™ RCA-based linear DNA offers superior IVT performance while eliminating key drawbacks of plasmid-derived templates:

  • Pre-validated Poly(A) integrity – Ensuring stable and efficient mRNA synthesis
• Can GenXceed™ support customized mRNA template designs?

  Absolutely. Our platform offers flexible design options, including:

  • Custom Poly(A) Tail Lengths – Tailored to enhance IVT efficiency for specific applications
  • Vector Optimization – Ensuring the highest yield and stability for mRNA synthesis
  • Sequence Modifications – Supporting specialized research and therapeutic needs
