Several techniques are used to detect aberrant gene expression: 1. Quantitative PCR (qPCR): This technique quantifies gene expression levels by measuring the amount of mRNA. 2. Microarrays: These can analyze the expression levels of thousands of genes simultaneously. 3. RNA-Seq: A powerful tool that provides a comprehensive view of the transcriptome by sequencing RNA molecules. 4. Immunohistochemistry: This method detects protein expression in tissue samples using specific antibodies.
