The Phenotype MicroArray (PM) system and software were developed by the same experts at Biolog that pioneered modern phenotypic identification of bacteria and fungi. Using much of what was learned from our identification work we expanded the technology to provide extremely detailed phenotypic testing of cells for genomics, drug development, toxicology, cell fingerprinting, and other research applications.

Phenotype MicroArray panels of up to 1,920 phenotypic tests have been developed for:
Gram negative bacteria
Gram positive bacteria
Yeast and filamentous fungi
Mammalian cells
