Product Guide – IncuCyte® NucLight Rapid Reagents for Nuclear Labeling
The IncuCyte® NucLight Rapid NIR Reagent for nuclear labeling is a cell permeable DNA stain that specifically stains nuclei in cells and is ideally suited to the mix-and-read, real-time quantification using the IncuCyte® Live-Cell Analysis System. Addition of the IncuCyte NucLight Rapid NIR Reagent to normal healthy cells is non-perturbing to cell growth and morphology and provides homogeneous staining of nuclei, enabling the real-time, fluorescent quantification of cell proliferation. When added to cell culture medium, the inert stain crosses the cell membrane and has excellent specificity for DNA without the need for a wash step. With the IncuCyte® integrated analysis software, fluorescent objects can be quantified and background fluorescence minimized. This reagent can be multiplexed with IncuCyte® Annexin V, Caspase-3/7 or Cytotox Reagents for simultaneous readouts of apoptosis or cytotoxicity alongside cell proliferation. The IncuCyte NucLight Rapid NIR Reagent has been validated for use with IncuCyte® Live-Cell Analysis Systems configured with an Orange/NIR Optical Module.

NucLight Rapid Red Reagent is non-perturbing and enables high-efficiency labeling of cell nuclei
Figure 2 Representative images and data of MDA-MB-231 labeled with IncuCyte NucLight Rapid NIR. Note the homogeneous nuclear restricted labeling by the NIR dye (pseudo-colored blue) and the healthy cell morphology. Data shows equivalent cell growth profiles to non-labeled cells.
Multiplex with cell health reagents for additional insight
Figure 3 Representative images of control (top-left) or camptothecin-treated (top-right) Jurkat cells labeled with NucLight Rapid NIR reagent and Annexin V orange after 48 hour culture. Cell death (apoptosis) is monitored in real time by measuring the loss of NIR object count (bottom-left) and increase of orange object area (Annexin V signal, bottom-right) over time.
