C47H51N3O22

1009.93

Chemical. CAS: 112926-02-0. Formula: C47H51N3O22. MW: 1009.93. Synthetic. INDO 1-AM is a popular non-invasive UV-excitable calcium indicator. It is the cell-permeable ester derivative of INDO 1. After crossing the cell membrane, INDO 1-AM is rapidly hydrolyzed by cytoplasmic esterases to produce the ratiometric fluorescent calcium indicator INDO 1, which remains trapped within the cell. INDO 1/AM has been used to selectively monitor Ca2+ levels in mitochondria and in the cytosol. INDO 1 is ideal for analyses using flow cytometry, as it uses a single excitation source (usually the 351-364nm spectral lines of the argon-ion laser). In contrast to FURA 1, INDO 1 has a dual emission peak. The emission of INDO 1 shifts to 400nm (when bound to Ca2+) from 480nm in Ca2+-free environments. INDO 1 is prone to photobleaching, which limits its usefulness in methods involving microscopy. Calcium measurement is critical for numerous biological investigations. Fluorescent probes that show spectral responses upon binding Ca2+ have enabled researchers to investigate changes in intracellular free Ca2+ concentrations by using fluorescence microscopy, flow cytometry, fluorescence spectroscopy and fluorescence microplate readers. Spectral Data: lambdaex 330nm; lambdaem 450nm (with Calcium), lambdaex 356nm; lambdaem 478nm in methanol. - INDO 1-AM is a popular non-invasive UV-excitable calcium indicator.
