These are then spun down and resuspended in 50ul of MACS buffer before 05ul of livedead stain is added. Unlike other commonly used nuclear stains such as propidium iodide PI or DRAQ7 Live-or-Dye NucFix labeling is covalent so the.
In a round bottomed well 2 drops of the positive and 2 drops of the negative beads are added.
Zombie live dead stain. Advertentie Dont compromise your research. Use dead cell stains for accurate results. Zombie Aqua is an amine-reactive fluorescent dye that is non-permeant to live cells but permeant to cells with compromised membranes.
Thus it can be used to assess live vs. Dead status of mammalian cells. Zombie Aqua is a polar water-soluble dye providing very bright green fluorescence making it suitable for use in multi-color detection.
As Martin has correctly pointed out zombie dyes stain only the surface protein in the live cells. It appears that you are using a higher concentration of dye and thats probably the reason why you. I used Zombie aqua dye fixable viability dye for the first time to stain splenocytes by Flow cytometry.
I mixed the live cells with heat killed cells heated at 65 degrees for 1 min in 11 ratio. The LIVEDEAD Fixable Near-IR stain was selected based on its fluorescent properties to provide a bright signal when excited with a red laser. The near-IR fluorescent reactive dye has an excitation maximum of 633 nm making it ideal for use with the red or HeNe laser with an emission of 750 nm.
LIVEDEAD Fixable Dead Cell Stain kits are fixable viability dyes that distinguish live cells from dead cells based on cell membrane integrity and access to available amines. Cells can then be fixed for intracellular antigen detection without loss of original cell staining pattern. Using a livedead stain is crucial to determining what percentage of your sample is live and what percentage is dead.
When using a livedead stain cell populations can be identified more easily and provide a clearer image of the cell viability in your sample. By using a live dead stain you can remove the cells that could be reporting a false signal and therefore be more confident in your data. The Live Dead assay staining solution is a mixture of two fluorescent dyes that differentially label live and dead cells.
The Live cell dye labels intact viable cells green. It is membrane permeant and non-fluorescent until ubiquitous intracellular esterases. Unlike titrating antibodies where the goal is to determine the lowest concentration to get a maximal staining index the fixable viability dyes should be titrated down until the live cells are not showing the signature for the dye Figure 6.
Dont forget that a mixture of both live and dead cells should be stained for a titration experiment.

Live cell with dye bound to surface primary amines.
Dead cell with dye bound to surface and intracellular primary amines. The benefit of these dyes is that once the cells are stained with the viability dyes they can be fixed they can also be used unfixed without any reduction in the resolution between live and dead cells. 436 Zombie Violet eFluor 450 VioBlue Pacific Blue LiveDead Violet BV480 eFluor 506 BV510 VioGreen Zombie Aqua LiveDead Aqua BV570 Pacific Orange LiveDead Yellow Super Bright 600 BV605 Zombie Yellow BV650 Super Bright 645 Qdot655 Super Bright 702 BV711 Qdot705 BV750 BV785 Qdot800 Qdot605.
Live-or-Dye NucFix Red is a unique cell membrane impermeable dye that specifically stains the nuclei of dead cells. Unlike other commonly used nuclear stains such as propidium iodide PI or DRAQ7 Live-or-Dye NucFix labeling is covalent so the. BD Horizon Fixable Viability Stain 450 FVS450 is useful to discriminate viable from non-viable mammalian cells in multicolor flow cytometric applications.
This violet fluorescent stain contains a dye that reacts with and covalently binds to cell surface and intracellular amines. Permeable plasma cell membranes such as those present in necrotic. These beads are only used for one well to compensate for the livedead fixable stain.
In a round bottomed well 2 drops of the positive and 2 drops of the negative beads are added. These are then spun down and resuspended in 50ul of MACS buffer before 05ul of livedead stain is added.
