ORANGE-NHS LIVE CELL PH DYE (1EA= 1MG) (C005B-314863)

General description

The BioTracker Apo-15 Calcium-Independent Apoptosis Probe is a calcium-independent, “turn-on” fluorescence probe emitting in the green spectrum for imaging and detection of apoptotic live cell under wash-free conditions. Like Annexin V, Apo-15 binds phosphatidylserine (PS) during early stage apoptosis when PS is translocated to the outer plasma membrane (Barth, 2020).
Apoptosis is dysregulated in numerous diseases, from inflammatory conditions to cancer. Detection of apoptosis is a key output in assessing drug efficacy, yet the low levels of free calcium in diseased tissues limit use of annexins as apoptosis detection reagents, favoring calcium-independent fluorogenic detection. Apo-15 binds negatively-charged phospholipids exposed on apoptotic cell membranes without interfering with cellular function. Apo-15 is non-fluorescent in viable cells but highly fluorescent in apoptotic cells, enabling highly specific detection of early apoptosis. Apoptotic imaging and detection with Apo-15 is broadly applicable to a wide range of cell types and experimental conditions.
Spectral Properties
Fluorescence images obtained by λex = 500 nm and emission at 520 nm.
