Biolog OmniLog phenotype microarray system

OmniLog Phenotype Microarray System

As part of the Wellcome Trust ISSF award (, the Biosciences department operates a Biolog OmniLog phenotype microarray system. The OmniLog PM system can simultaneously evaluate thousands of phenotypes in microbial cell-based assays, with the ability to incubate fifty 96-well microplates at any one time. The system is primarily used for determining function of gene knockouts/mutants.

Example projects which have used the OmniLog system include testing the function of unidentified nitrogen compound-degrading enzymes and evaluating the substrates for heterologously-expressed fungal transporters in Saccharomyces cerevisiae (budding yeast).

See the Exeter OmniLog webpages for more information on using this facility.
