Service Overview

Precise Genome Editing Without Double-Strand Breaks

Base editing enables precise single-nucleotide changes without creating risky DNA double-strand breaks, offering a safer alternative to traditional CRISPR-Cas9.

What is Base Editing?

Base editing uses a modified Cas9 protein fused to a deaminase enzyme to chemically convert one DNA base to another. Unlike traditional CRISPR, no DNA double-strand breaks are created, eliminating the risk of chromosomal rearrangements and unwanted indels.

  • Cytosine base editors: C→T conversions
  • Adenine base editors: A→G conversions
  • Prime editors: All 12 mutation types

Why Choose Our Service?

We provide comprehensive base editing services with expert gRNA design, high-quality reagents, and thorough quality control. Our team helps you select the optimal base editor and delivery strategy for your specific research or therapeutic goals.

  • Multiple base editor platforms available
  • Comprehensive off-target analysis

FAQ

Frequently Asked Questions

Find answers to common questions about our service.

Which base editor should I choose for my target mutation?
Choose CBE (cytosine base editor) for C→T or G→A conversions. Choose ABE (adenine base editor) for A→G or T→C conversions. For other mutation types or small indels, prime editing is recommended. Our team can help you select the optimal base editor based on your specific target sequence and mutation type.
What is the typical editing efficiency?
Editing efficiency varies depending on the target site, cell type, and base editor used. Typically, we observe 30-70% editing efficiency for well-designed targets in standard cell lines. Our gRNA design service optimizes for maximum efficiency while minimizing off-target effects.
What quality control is included?
Every project includes comprehensive QC: NGS analysis for on-target editing efficiency, GUIDE-seq or similar for off-target DNA analysis, RNA-seq for transcriptome-wide off-target assessment, and indel profiling. You receive a detailed QC report with all metrics and raw data.
What delivery formats are available?
We offer multiple delivery formats: plasmid DNA (research grade), mRNA + synthetic gRNA (improved safety), RNP (ribonucleoprotein) complexes (transient editing, lowest off-target), and LNP formulations (in vivo applications). Our team can recommend the best format for your specific application.
What is the typical turnaround time?
Turnaround time ranges from 2-8 weeks depending on project complexity. Simple gRNA design and validation projects typically take 2-3 weeks. Full service including base editor construction, delivery, and comprehensive QC analysis may take 4-8 weeks. Expedited services are available upon request.
Do you provide design consultation?
Yes, expert design consultation is included with every project. Our team will help you select the appropriate base editor, design optimal gRNAs, predict off-target sites, and plan the experimental workflow. We work closely with you to maximize success based on your specific research goals.
