Micro array is a tool used in laboratory to detect the expressions of thousands of genes at the same time. Micro array technology has extensive application in Pharmacogenomics. Comparative analysis of the genes from a diseased and a normal cell will help to identify the biochemical constitution of the proteins which are synthesized by the diseased genes. The researchers can use this information for synthesizing drugs that combat with these proteins and reduce their effect.
DNA micro array technology helps in the identification of new genes, to learn more about the diseases like heart diseases, mental illness, infectious disease and especially the study of cancer.
