This study presents a robust array-based comparative genomic hybridization (aCGH) protocol for analyzing single cancer cell genomes. The method reliably detects copy number alterations (CNAs) crucial for cancer research and diagnostics.
Area of Science:
- Genomics
- Oncology
- Molecular Biology
Background:
- Single-cell genome analysis is vital for clinical diagnostics and cancer research.
- Understanding tumor heterogeneity, circulating tumor cells (CTCs), and disseminated cancer cells (DCCs) necessitates single-cell genomic analysis.
Purpose of the Study:
- To develop and present a reliable and robust array-based comparative genomic hybridization (aCGH) protocol.
- To enable the detection of copy number alterations (CNAs) in single cancer cells.
Main Methods:
- Utilized Ampli 1™ whole genome amplification.
- Employed array-based comparative genomic hybridization (aCGH).
Main Results:
- Successfully established a reliable and robust aCGH protocol.
- Demonstrated the detection of copy number alterations (CNAs) in single cancer cells.
- Achieved detection of CNAs as small as 100 kb.
Conclusions:
- The described aCGH protocol is effective for single-cell cancer genomics.
- This method supports advancements in cancer research and clinical applications like diagnostics.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
