ION Biosciences IPG-4 AM
Yellow-green fluorescent, potassium (K+) indicator, membrane permeable.
Higher K+ affinity than IPG-1 and IPG-2
ION Potassium Green – 4 (IPG-4) is a yellow-green fluorescent, intracellular potassium (K+) indicator with Ex/Em: 525 nm/545 nm and a high-sensitivity to detect small changes in K+ concentration. IPG-4 has the highest affinity (Kd = 7 mM) among IPG analogues – IPG-2 (Kd = 18 mM) and IPG-1 (Kd = 50 mM).Item#:

ION Biosciences BAPTA AM
Non-fluorescent calcium (Ca²+) chelator, membrane permeable.
BAPTA AM is a highly selective, intracellular calcium (Ca²+) chelator that is less sensitive to pH fluctuations than EGTA and EDTA. Can be used to modulate the level of intracellular Ca²+.

SBFI K+ SALT
Ratiometric sodium (Na+) indicator, membrane impermeable.
SBFI is a UV-excitable, ratiometric green indicator for intracellular sodium (Na+) measurements. Ex/Em: 340/505 nm can be used to measure Na+-bound SBFI, and Ex/Em: 380/505 nm can be used to detect Na+-free SBFI. It is ~18X more selective for Na+ over K+. Ratiometry is optimal for imaging applications where quantification of intracellular Na+ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
SBFI K+ salt is a membrane impermeable form of SBFI that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.

ION Biosciences Fluo-4 K+ Salt
Fluo-4 K+ Salt is a membrane impermeable form of Fluo-4 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
Green fluorescent, calcium (Ca²+) indicator, membrane impermeable.
Fluo-4 is the most popular green fluorescent, calcium (Ca²+) indicator. Proven and trusted for decades to measure intracellular Ca²+ flux in high throughput screening and fluorescence microscopy applications.
Fluo-4 K+ Salt is a membrane impermeable form of Fluo-4 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.

ION Vital - Viability Kit
Two-color, fluorescence-based assay to discriminate between live and dead cells.
ION Vital – Viability kit can be used to quantify live and dead cells within eukaryotic cell suspensions or adherent cultures, 3D cultures, organoids, and some non-fixed tissues. Cannot be used for yeast or bacteria. When following our protocol, ION Vital—Viability kit provides enough reagents to make 150 mL of working solution, enough for fifteen 96-well plates or 1,500 flow cytometry samples. The actual number of assays will vary according to optimal dye concentrations for your application.

ION Biosciences PBFI K+ Salt
PBFI is a UV-excitable, ratiometric green indicator for intracellular potassium (K+) measurements. Ex/Em: 340/505 nm can be used to measure K+-bound PBFI, and Ex/Em: 380/505 nm can be used to detect K+-free PBFI. It is 1.5X more selective for K+ over Naand works well in cytosolic conditions where [K+]/[Na] is ~10. Ratiometry is optimal for imaging applications where quantification of intracellular K+ concentrations is desired and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
