HAYWARD, Calif.--Biolog, which calls itself a new entrant to the genomics and phenomics fields, has been issued a US patent for a use for its gene-function determination technology, Phenotype MicroArray. Inventor Barry Bochener, Biolog's chairman, said the technology allows simultaneous quantitative measurements of thousands of cellular phenotypes. The patented method for determining gene function employs comparative phenotype analysis to directly measure the consequence of a genetic change.
