The Violet Ratiometric Membrane Asymmetry Probe⁄Dead Cell Apoptosis Kit provides a simple and fast method for the detection of apoptosis with dead cell discrimination by flow cytometry. The Violet Ratiometric Membrane Asymmetry Probe, 4'-N,N-diethylamino-6-(N,N,N-dodecyl-methylamino-sulfopropyl)-methyl-3-hydroxyflavone (F2N12S), is a novel violet excitable dye for the detection of membrane asymmetry changes during apoptosis. The dye exhibits an excited-state intramolecular proton transfer (ESIPT) reaction resulting in a dual fluorescence with two emission bands corresponding to 530 nm and 585 ...

The LIVE/DEAD® Fixable Dead Cell Stain Kit employs an amine-reactive fluorescent dye to evaluate mammalian cell viability by flow cytometry. In cells with compromised membranes, the dye reacts with free amines both in the cell interior and on the cell surface, yielding intense fluorescent staining. In viable cells, the dye's reactivity is restricted to the cell-surface amines, resulting in less intense fluorescence. The difference in intensity between the live and dead cell populations is typically greater than 50 fold, and this fluorescence intensity discrimination is completely preserved fol...

The LIVE/DEAD® Violet Viability/Vitality Kit provides a two-color fluorescence cell viability and vitality assay that is based on the simultaneous determination of live and dead cells with two probes that measure recognized parameters of cell health: plasma membrane integrity and intracellular esterase activity. Calcein violet AM and aqua-fluorescent reactive dye are optimal dyes for this application; both dyes utilize the violet laser allowing other laser lines to be used for conventional fluorochromes.

The Premo™ Autophagy Sensor RFP-p62 Kit combines the ability to monitor the induction or inhibition of autophagy, through the localization of the autophagy receptor p62 (also known as SQSTM1), with the high transduction efficiency and minimal toxicity of BacMam 2.0 technology. To perform an image-based analysis for autophagy, simply add the BacMam 2.0 RFP-p62 reagent to your mammalian cells, incubate overnight to ensure adequate protein expression, and then visualize using standard RFP (red fluorescent protein) settings. The RFP gene included in this chimera is mKate2. This monomeric fluoresce...
