Invitrogen™ eBioscience™ Indo-1 AM Calcium Sensor Dye

Catalog No. 50-169-56

Supplier: Invitrogen™ 65085639

Description

Membrane-permeable dye used to determine changes in calcium concentrations in the cell using fluorescence microscopy, flow cytometry, fluorescence spectroscopy and fluorescence microplate readers. Once Indo-1 enters the cell, esterases cleave the AM group yielding a membrane-impermeable dye.

• Unbound Indo-1 has a peak emission at 475nm
• Upon binding calcium, peak emission shifts down to 410nm
• In flow cytometry this can be measured over time and can be represented as a ratio of the two emission wavelengths
• To optimize the ratio between the two emissions, unbound Indo-1 fluorescence should be collected using a filter above 485nm; bound Indo-1 fluorescence should be collected using a filter below 400nm
• Because the emission profile of Indo-1 is broad, multicolor flow analysis using eFluor ™ 450, eVolve™ 605 or eVolve™ 655 is not possible, however fluorochrome conjugated antibodies utilizing the 488nm or 633 nm are quite compatible with Indo-1
