Seahorse Core

The Seahorse Core falls under the Cardiovascular Flow Core and supports the use of an XFe24 Extracellular Flux Analyzer from Seahorse Biosciences to perform sensitive measurements of oxygen consumption rate and extracellular acidification rate in cultured cells, tissues, or model organisms in a 24-well format.

Equipment: XFe24 Extracellular Flux Analyzer, Prep Station


  1. Basic Assay – core provides assay plate and assay cartridge – user provides samples in the assay plate, assay medium, and injection reagents
  2. Glyco Stress Assay – core provides assay plate, assay cartridge, Seahorse medium with supplements, and Seahorse reagents – user provides samples in the assay plate. BY APPOINTMENT ONLY.
  3. Mito Stress Assay – core provides assay plate, assay cartridge, Seahorse medium with supplements, and reagents – user provides samples in the assay plate

All services include use of the Seahorse Prep Station liquid handling system and non-CO2 incubator, cartridge hydration on the day prior to the assay, and technical assistance. Users are responsible for preparing media and injection reagents, performing media exchanges, loading the assay cartridges, running the assay, and analyzing the data. All new users require training.
