GEN III Test Panel

The Microbial Identification Test Panel (GEN III Microplate) uses 94 unique biochemical tests to profile and identify a broad range of gram-negative and gram-positive bacteria.

  • Analyze an unknown microorganism with 94 simultaneous phenotypic tests. The test panel provides a “Phenotypic Fingerprint” of the microorganism that is used to identify it at the species or strain level.
  • All necessary nutrients and biochemicals are prefilled and dried into the 96-wells microplate. Redox dyes with colorimetric indicators enable a sensitive assay to screen the utilization of the carbon sources or resistance to inhibitory chemicals.
  • Grow your isolate on agar medium and then suspend it in our inoculating fluid. Transfer it to the GEN III Microplate and incubate. If the cells can utilize the unique substrate or are not susceptible to the inhibitor chemicals in each well, they will respire and cause the dye to change to a purple color. During incubation, the phenotypic fingerprint of purple wells is compared to Biolog’s extensive database. A species- or strain-level identification of the isolate is made when a match is found.

When using Biolog’s microbial identification microplates, the right system can help you interpret your results to ensure correct identification.  Depending on your level of throughput, we offer different solutions to support your needs: 

  • Odin™ family  Fully automated incubator/readers with up to an 8-plate capacity (Odin VIII) or a 50-plate capacity (Odin L) with software that can identify aerobic and anerobic bacteria, yeast, and filamentous fungi. 
  • ID Station™  A single plate reader with a software package that can identify aerobic and anerobic bacteria, yeast, and filamentous fungi.
