What Techniques are Used to Determine Gene Expression Profiles?
Several techniques are employed to analyze gene expression profiles, including:
- Microarrays: These consist of a grid of DNA sequences that can hybridize with mRNA from the sample, allowing researchers to measure the expression levels of thousands of genes simultaneously. - RNA Sequencing (RNA-Seq): This next-generation sequencing technique provides a more comprehensive and precise measurement of gene expression by sequencing cDNA derived from RNA.
