Microarray technology is a high-throughput genomic technique used to analyze thousands of genes or genetic markers simultaneously. It is widely used in gene expression analysis, SNP genotyping, disease research, biomarker discovery, and functional genomics.
What is a Microarray?
A DNA microarray contains thousands of specific DNA probes arranged on a solid surface. DNA or RNA from a biological sample binds to complementary probes, allowing researchers to measure gene expression or detect specific genetic variations.
How Does Microarray Analysis Work?
A typical microarray workflow includes:
Sample Collection → DNA/RNA Extraction → Labeling → Hybridization → Scanning → Data Analysis
The resulting data can be analyzed to identify differentially expressed genes, genetic variants, molecular signatures, and biological pathways.
Applications of Microarray Technology
Microarrays are commonly used for:
- Gene expression profiling
- SNP genotyping
- Cancer and disease research
- Biomarker discovery
- Pharmacogenomics
- Comparative genomic studies
- Functional genomics
SNP microarrays can analyze large numbers of known genetic variants, while gene expression arrays allow researchers to compare expression patterns across thousands of genes.
Microarray vs NGS
Microarrays are particularly useful when researchers want to analyze a predefined set of genes or genetic markers in a cost-effective, high-throughput format. NGS, on the other hand, provides sequence-level information and greater potential for discovering novel variants and transcripts. Therefore, the choice between Microarray and NGS depends on the research objective, required resolution, sample numbers, and budget.
