RT Journal A1 Xu, C. Wilson T1 High-Density Cell Microarrays for Parallel Functional Determinations JF Genome Research JO Genome Research YR 2002 FD March 01 VO 12 IS 3 SP 482 OP 486 DO 10.1101/gr.213002 UL http://genome.cshlp.org/content/12/3/482.abstract AB Whole-genome sequencing projects have generated a wealth of gene sequences from a variety of organisms. A major challenge is to rapidly uncover gene regulatory circuits and their functional manifestations at the cellular level. Here we report the coupled fabrication of nanocraters ranging in size from 100 pL to 1.5 nL on permeable membranes for culturing cells. Using this approach, we developed bacterial and yeast cell microarrays that allowed phenotypic determinations of gene activities and drug targets on a large scale. Cell microarrays will therefore be a particularly useful tool for studying phenotypes of gene activities on a genome-wide scale.
