An Overview on Gene Expression Analysis

Abstract

Recent advances in DNA microarray technology, also known as gene chips, allow measuring the expression of thousands of genes in parallel under multiple experimental conditions [1]. This technology is having a significant impact on genomic studies. Disease diagnosis, drug discovery and toxicological research benefit from the microarray technology. Arrays are now widely used in basic biomedical research for mRNA expression profiling and are increasing being used to explore patterns of gene expression in clinical research.
