ION Vital kits are designed to help you easily capture important markers of cell health, whether your preferred instrument is a plate reader, fluorescence microscope, or flow cytometer, using a collection of criteria that are indicative metrics of cell viability or death. These criteria include intracellular esterase activity as a marker of cell viability, plasma membrane integrity as a marker of cell death, and mitochondrial membrane potential as an early-stage marker of apoptosis. When used in combination, these assays can provide an informative snapshot of cell health.
ION VITAL – Viability Kit
ION VITAL Viability Kit is a rapid and simple two-color assay to discriminate between live and dead cells within eukaryotic cell suspensions or adherent cultures. Calcein AM measures intracellular esterase activity and ethidium homodimer is a marker of plasma membrane integrity. The kit can be used with flow cytometers, fluorescence microscopes, and fluorescence plate readers.
ION VITAL – MitoVolt
ION VITAL – MitoVolt is a ratiometric, fluorescence-based assay to assess mitochondrial membrane potential in cells. Our mitochondrial membrane potential assay kit uses JC-10, a membrane potential sensitive dye that is more soluble than JC-1. The cationic, lipophilic JC-10 dye concentrates in polarized mitochondrial matrices, producing red fluorescent J-aggregates. On the other hand, JC-10 diffuses out of depolarized mitochondria in apoptotic and necrotic cells, where it converts back into a monomeric form that emits green fluorescence.
ION Essentials Ratiometric Calcium
The necessary reagents for conducting no wash, ratiometric calcium flux assays compatible with plate reader and fluorescence microscopy applications. Individual components are provided to give the user the flexibility needed to customize your assay.
Ratiometric Calcium Essentials kit provides the necessary reagents for conducting no wash, ratiometric calcium flux assays compatible with plate reader, and fluorescence microscopy applications. Individual components are provided to give the user the flexibility needed to customize your assay.
Fura-2 is the most popular UV-excitable, ratiometric green indicator for intracellular calcium (Ca²⁺) measurements. Ex/Em: 340/505 nm can be used to measure Ca²⁺-bound Fura-2, and Ex/Em: 380/505 nm can be used to detect Ca²⁺-free Fura-2.
Ratiometry is not only optimal for imaging applications where quantification of intracellular Ca²⁺ concentrations is desired, it also reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
Multidrug Resistance Activity Kit
ION’s Multidrug Resistance (MDR) Activity kit is an effective solution for detecting MDR1 and MRP1 activity and compounds susceptible to MDR-mediated efflux. ION’s MDR activity kit is compatible with fluorescence microscopy, flow cytometry and fluorescence microscopy, flow cytometry, and fluorescence plate readers using FITC/GFP settings.
Calcein AM is a membrance-permeant, non-fluorescent dye that enters cells passively. Once inside the cytosol of cells, intracellular esterases convert it to fluorescent Calcein (Ex/Em: 495 nm/515 nm), resulting in uniform cytosolic fluorescence. Drug efflux transporters, such as P-glycoprotein (Pgp, MDP1) and multidrug-resistance-associated protein (MRP1), actively extrude Calcein AM from inside the cell before esterases can convert it to Calcein. The presence of additional MDR substrates or inhibitors of MDR expression results in decreased Calcein AM efflux, causing a measurable increase in intracellular fluorescence. In addition to identifying MDR substrates and inhibitors, this kit can also be used to evaluate the activity of MDR transporters in cells.
When following our protocol, ION’s MDR Activity kit provides enough reagents to make 100 mL of working solution, enough for ten 96- or 384-well plates or 80 flow cytometry samples. The actual number of assays will vary according to optimal dye concentrations for your application.
