A DNA chip, also known as a microarray, is a tool used in genomics to measure the expression of thousands of genes simultaneously. It is a small glass slide or silicon chip that contains thousands of microscopic spots of DNA, each representing a specific gene. DNA chips are used to measure the expression of genes in a sample, allowing researchers to identify which genes are active and which are not. This technology has enabled researchers to gain a better understanding of the genetic basis of diseases, as well as to develop new treatments. DNA chips have also been used to identify genetic markers associated with certain diseases, allowing for more accurate diagnosis and treatment. Additionally, DNA chips have been used to identify genetic variations between individuals, allowing for personalized medicine. The DNA chip market is an important part of the genomics industry, as it provides researchers with the tools they need to study the genetic basis of diseases. Companies in the DNA chip market include Illumina, Thermo Fisher Scientific, Agilent Technologies, and Fluidigm. Show Less Read more
