Incucyte® Annexin V NIR Dye for Apoptosis

Incucyte® Annexin V NIR Dye for Apoptosis

One vial of lyophilized solid sufficient for 100-200 live-cell apoptosis tests in 96-well format.
(Cat. No. 4768)

The Incucyte® Annexin V NIR Dye is a highly-selective phosphatidylserine (PS) cyanine fluorescent dye. Specially formulated, this reagent is ideally suited for real time measurements of apoptosis in living cultures. Annexin V NIR Dye has been validated for use with IncuCyte® Live-Cell Analysis Systems configured with an Orange/NIR Optical Module or a Green/Orange/NIR Optical Module. It is not compatible with IncuCyte instruments paired with a Red/Green Optical Module (e.g. Cat. No 4647). Addition of the Annexin V NIR Dye to normal healthy cells is non-perturbing to cell growth and morphology and yields little or no intrinsic fluorescent signal. Once cells become apoptotic, plasma membrane PS asymmetry is lost. PS exposure on the extracellular surface enables binding of the Annexin V NIR Dye resulting in a bright and photostable fluorescent signal. With the IncuCyte® integrated analysis software, fluorescent apoptotic cells can be quantified and background fluorescence minimized.

Annexin V NIR Dye enables real-time evaluation of PS exposure in response to pharmacological agents and/or genetic and environmental factors. Furthermore, the Annexin V Dye can be combined with the Incucyte® confluence metric for multiplexed measurements of apoptosis and cell proliferation in every assay well.
