靶点与抗体说明

BD Horizon™ Fixable Viability Stain 440UV (FVS440UV) is useful for discrimination of viable from non-viable mammalian cells in multicolor flow cytometric applications. This dye reacts with and covalently binds to cell-surface and intracellular amines. Permeable plasma cell membranes, such as those present in necrotic cells, allow for the intracellular diffusion of the dye and covalent binding to higher overall concentrations of amines than in non-permeable live cells. Therefore, necrotic cells present in a typical in vitro assay label with higher levels of dye increasing their fluorescence intensity 10-20 fold over that of viable cells. The labeled cells can be fixed with formaldehyde for downstream decontamination, freezing and/or permeabilization and subsequent intracellular staining while maintaining stable viability stain fluorescence. BD Horizon™ Fixable Viability Stain 440UV is excited by the UV laser (with an excitation maximum of 338 nm), and has a fluorescence emission maximum of 436 nm. Danger: Hazard statement - Causes serious eye damage. Precautionary statements - Wear eye protection / face protection. Wash thoroughly after handling. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immedia
