ION Biosciences PBFI AM
 
PBFI is a UV-excitable, green ratiometric 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 Na, and 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.

VitroGel® STEM
 

ready-to-use, xeno-free (animal origin-free) hydrogel system for hPSCs 3D static suspension culture and scale-up

  • Establish stem cell spheroids directly from liquid nitrogen (5 min protocol)
  • High-quality 3D stem cells for differentiation and organoid formation
  • Easy scale-up (from laboratory scale to industrial scale)
  • Efficient cell harvesting or subculturing

VitroGel® STEM is a xeno-free (animal origin-free) hydrogel system developed to improve the performance of three-dimensional (3D) static suspension cultures and scale-up of human pluripotent stem cells (hPSCs) to create a high-throughput system to model various tissue and disease states.

This hydrogel system is ready to use with an optimized formulation that fully supports the rapid expansion of high-quality 3D stem cell spheroids with pluripotent properties. hPSCs directly thawed from liquid nitrogen or passaged from 2D matrix coated culture vessels can be immediately mixed with the hydrogel solution for static suspension cultures. Moreover, the optimization protocol is ideal for time-sensitive experiments, as it does not require excessive medium exchanges, which can ultimately save on time and materials. This hydrogel system is compatible with most hPSC culture media and tissue culture vessels. Due to the unique static suspension culture procedure, the requirement for microcarriers for large-scale bioreactors is eliminated, making cell harvesting simple and effective. The 3D stem cell spheroids that are developed using this system can be used for further sub-cultures, patterned differentiations, organoid development, or re-establishing 2D culture morphologies.

“Just add cells” 5 min protocol. No matrix coating required.

VitroGel® STEM is ready-to-use. Just mix with your hPSCs. There is no laborious matrix coating required to maintain and expand your stem cells.

ION Biosciences ING-2 AM

Yellow-green fluorescent, sodium (Na+) indicator, membrane permeable. Higher Na+ affinity than ING-1.
 
ION Natrium Green – 2 (ING-2) is a yellow-green fluorescent, intracellular sodium (Na+) indicator with improved cellular loading and significantly higher brightness than SBFI. Its spectral properties (Ex/Em: 525 nm/545 nm) and large dynamic range make ING-2 the best Na+ indicator for high-throughput screening applications targeting Na+ channels, and non-selective monovalent cation channels. ING-2 has a more physiologically relevant affinity (Kd = 20 mM) than ING-1 (Kd = 92 mM). Also compatible with fluorescence microscopy using common fluorescein, GFP or more ideally YFP filters.

ION Biosciences Fura-2 LR AM
 
Leakage-resistant, ratiometric calcium (Ca²+) indicator, membrane permeable.
 
UV-excitable, ratiometric green indicator for intracellular calcium (Ca²+) measurements with longer cellular retention compared to Fura-2 AM and similar spectral properties. 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 optimal for imaging applications where quantification of intracellular Ca²+ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
ION Biosciences ICR-1 AM

Red fluorescent, calcium (Ca²+) indicator, membrane permeable. Optimal for multiplexing and tissue imaging. Fluorescence lifetime and multiphoton compatible.
 
ION Calcium Red – 1 (ICR-1) is a red fluorescent (Ex/Em 580nm/660nm) calcium (Ca²+) indicator for intracellular Ca²+ measurements.

ICR-1’s long-wavelength emission and a large Stokes shift reduces contributions of autofluorescence, making ICR-1 AM optimal for cellular and tissue imaging applications. ICR-1 can also be multiplexed with GFP-labeled cells or other green fluorophores commonly used in experiments. Unlike some other red fluorescent Ca²+ indicators, ICR-1 does not accumulate in the mitochondria. Data supporting fluorescence lifetime imaging and multiphoton imaging capabilities have also been demonstrated.
ION Biosciences Fluo-4 AM

Green fluorescent, calcium (Ca²+) indicator, membrane permeable.
 
Fluo-4 is the most popular green fluorescent, intracellular calcium (Ca²+) indicator. Proven and trusted for decades to measure intracellular Ca²+ flux in high throughput screening and fluorescence microscopy applications.
Calcein AM
 
Green fluorescent, live cell indicator.
 
Calcein AM is a membrane-permeant, non-fluorescent form of calcein that is converted to green fluorescent calcein in viable cells, resulting in uniform cytosolic fluorescence (Ex/Em 495 nm/515 nm). Calcein is well retained within the cytosol of most healthy cells with intact cell membranes.
