TempoVol^TM cationic voltage biosensors are incorporated into human neural progenitor cells. They respond to intracellular ionic changes in the 605nm-625nm fluorescent range (Excitation/Emission = 610nm/625nm), measuring increases or decreases in cytosolic calcium/potassium/proton/sodium concentrations. With excellent signal-to-noise ratios, these calcium biosensors can operate on second-to-minute scales. They can be used for single-cell applications, as well as medium to high-throughput screening platforms.

TempoVol™-iCort: cationic voltage biosensor assay using human iPS-derived . They are derived from integration-free induced pluripotent stem cell (iPSC) lines under a fully defined proprietary neural induction and maturation conditions. TempoVol™-iCort cells are polarized structures when plated as a monolayer in culture and express markers such as MAP2 and beta-Tuj. We've validated iCort™ cells to be cationic-conducting neurons when exposed to solutions with fluctuating concentrations of sodium, calcium, potassium, magnesium, and protons/H+. TempoVol™ biosensor is introduced to the cells using proprietary methods and is expressed in the in abundance in the cell.

TempoMito™-iNStem cells comprise mitochondrial biosensors incorporated into human iPS-derived neural progenitor cells. Mitochondrial dysfunctions have been implicated in human neurological and psychiatric disorders, and neural progenitor cells have been used as a cellular model. Tempo's biosensor responds to mitochondrial calcium changes and reports in the 605nm-625nm fluorescent range (Excitation/Emission) as calcium levels increase or decrease. With excellent signal-to-noise ratios, these sensors can operate on second-to-minute scales. This tool provides an efficient way of detecting changes in the mitochondrial organelle and enables high-throughput screening approaches for drug discovery and toxicology screening.
