Membrane-permeant, ratiometric Ca2+ indicator.
Membrane-impermeant, ratiometric Ca2+ indicator.
Membrane-permeant, non-fluorescent Ca2+ chelator.
Calcein AM is a membrane-permeant, non-fluorescent form of calcein that enters cells passively. Once inside the cytosol of cells, Calcein AM is converted to green-fluorescent Calcein by ubiquitous esterases in viable cells, resulting in uniform cytosolic fluorescence (Ex/Em 495 nm/515 nm)
Membrane-permeant Ca2+ indicator.Higher Ca2+ affinity than Fluo-3 or Fluo-4.
Membrane-impermeant Ca2+ indicator.Higher Ca2+ affinity than Fluo-3 or Fluo-4.
