High-throughput analyses of gene functions on a cell chip by electroporation.

Genome-wide functional annotation of genes is one of the major challenges in current biology. Such investigation requires a high-throughput methodology for efficient and parallel overexpression or silencing of multiplexed genes in living cells. The transfection method described here employs an electric pulse and a cell-chip technology, and provides the possibility of analyzing gene functions in a high-throughput manner.
