MDR 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 plate readers using FITC/fluorescein settings.

Calcein AM is a membrane-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, MDR1) 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.

ION Biosciences RATIOMETRIC CALCIUM ESSENTIALS
 
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.
ION Biosciences Fluo-3 AM

Green fluorescent, calcium (Ca²+) indicator, membrane permeable.
 
Fluo-3 is a green fluorescent, intracellular calcium (Ca²+) indicator with slightly red-shifted spectral properties compared to Fluo-4. Offers a large dynamic range that can be better suited for high contrast imaging applications. Is preferred over Fluo-4 for some cell types.
ION Biosciences IPG-1 AM

Yellow-green fluorescent, potassium (K+) indicator, membrane permeable.
 
Lower K+ affinity than IPG-2 and IPG-4.
 
ION Potassium Green – 1 (IPG-1) is the best in class yellow-green fluorescent, intracellular potassium (K+) indicator for measuring changes at most intracellular K+ concentrations. IPG-1 has Ex/Em: 525 nm/545 nm and a high-sensitivity to detect small changes in K+ concentration. IPG-1 has a lower affinity (Kd = 50 mM) than IPG-2 (Kd = 18 mM) or IPG-4 (Kd = 7 mM).
