Biochips for Gene Spotting

K. K. Jain

Biochips containing microarrays of genetic information promise to be important research tools in the postgenomic era. Because DNA microarray can contain many thousands of samples, each representing a single gene, it is possible to design a single chip containing the complete gene set of a complex organism (30,000 to 60,000 genes). DNA microarrays provide a powerful way to simultaneously analyze the expression of thousands of genes. This article describes the design and uses of microarrays of DNA.
