Cellular age and origin, in addition to donor variability, protocol differences, growth rates and media choices all contribute to inconsistent reprogramming and/or differentiation efficiencies. Metabolic energy utilization, characterized before and after cell fate changes occur, identifies the metabolic phenotype and enables researchers to predict and confirm cell function, revealing actionable reprogramming and differentiation potential.
Cellular metabolic phenotyping measures the cell’s energy requirement and pathway preference for readying the transition between undifferentiated and differentiated states. Metabolic switching occurs rapidly as cells transition from quiescent to pluripotent and/or from pluripotent to differentiated.

Identify Pluripotency and Differentiation Transitions
Seahorse XF technology enables reliable measurements that predict, monitor, and track cell fate transitions. Discover how these metabolic measurements can be used as indicators to minimize inefficiencies and improve differentiation and reprogramming approaches. Routine assays make identifying cell phenotype and cell transitions easy. What’s more, the metabolic phenotyping analysis that Seahorse XF delivers provides the tools and knowledge to customize your approach, and push the conventional boundaries of stem cell research through the development of new assays.

Seahorse XF Technology simultaneously measures rates of oxidative metabolism and glycolysis using label-free methods on live cells, in real-time.
“iPSCs and their differentiated counterparts are metabolically distinct and these metabolic parameters are important for stem cell identity.”

Seahorse XF Analyzers simultaneously measure the two major energy pathways of the cell — mitochondrial respiration and glycolysis — in live cells using label-free, solid-state sensor cartridges in a microplate format. They work with many cell types, including primary cells, cell lines, suspension cells, as well as islets, spheroids, and isolated mitochondria.
The patented design makes it all possible
Seahorse XF Analyzers utilize patented transient microchambers which enable sensitive, precise, and label-free metabolic measurements of live cells in real time.
Integrated injection ports sequentially deliver up to 4 compounds allowing multiple conditions per well.
Sensor probes gently lower to create a transient microchamber, allowing rapid, real time measurement of changes in both oxygen and proton concentrations in the extracellular medium.
Seahorse XF Cell Culture Microplates are tissue culture treated and plate reader compatible.
Inert optical microsensors measure rates of oxygen consumption and extracellular acidification simultaneously, without addition of dyes.
The microplate well requires a small number of cells, 10-20 fold fewer cells compared to conventional respirometers.

Measure What's Important to Your CellWith over 20,000 genes, 200,000 proteins and thousands of pathways, you can’t measure everything in a cell at once, but you can measure what provides the energy that drives them—metabolism.
Agilent Seahorse XF technology detects changes in cell bioenergetics in real-time, providing a window into the critical functions driving cell signaling, proliferation, activation, toxicity and biosynthesis.
Move beyond analyzing what your cells are, and reveal a clearer picture of what they do.
Agilent Seahorse Wave SoftwareWave, the primary Seahorse software program, enables the transformation of raw kinetic data into powerful results. Wave provides preloaded templates and protocols for each Seahorse XF assay kit, reducing time for assay design, as well as several analysis views and export options that facilitate Seahorse XF data analysis and interpretation.
