Live or Dead™ Fixable Dead Cell Staining Kit
Deep Red Fluorescence
Our Live or Dead™ Fixable Dead Cell Staining Kits are a set of tools for labeling cells for fluorescence microscopic investigations of cell functions. The effective labeling of cells provides a powerful method for studying cellular events in a spatial and temporal context. This particular kit is designed to uniformly label fixed mammalian cells in red fluorescence for long term microscopic examination. The kit uses a proprietary red fluorescent dye that is more fluorescent upon bonding to cellular components. The fluorescent dye used in the kit is quite photostable so that the images can be repeatedly examined. The kit provides all the essential components with an optimized cell-labeling protocol. It is an excellent tool for preserving of fluorescent images of particular cells, and can also be used for fluorescence microscope demonstrations.
Detection of Jurkat cell viability by Live or Dead™ Fixable Dead Cell Staining Kits (Cat#22604). Jurkat cells were treated and stained with Stain It™ Deep Red, and then fixed in 3.7% formaldehyde and analyzed by flow cytometry. Live (Blue), staurosporine treated (Green) and heat-treated (Red) cells were distinguished with APC channel.
