Invitrogen™ LIVE/DEAD™ Cell Imaging Kit (488/570)

Description

• Allows discrimination between live and dead cells with two probes that measure recognized parameters of cytotoxicity and cell viability: intracellular esterase activity and plasma membrane integrity Based on cell-permeable dye for staining of live cells and cell-impermeable dye for staining of dead and dying cells Adapted for imaging platforms by optimizing for common green and red imaging filters used with FITC and Texas Red Live cell component produces intense, uniform green fluorescence in live cells (ex/em 488 nm/515nm Dead cell component produces predominantly nuclear red fluorescence (ex/em 570nm/602nm) in cells with compromised cell membranes, strong indicator of cell death and cytotoxicity Sensitive detection of key measures of cell health: viability, live/dead ratio, and cytotoxicity Ease of use with minimal dilutions Live cells are distinguished by presence of ubiquitous intracellular esterase activity as determined by the enzymatic conversion of virtually nonfluorescent cell-permeant calcein AM to intensely fluorescent calcein, which is well-retained within live cells Red component is cell-impermeant and therefore only enters cells with damaged membranes In dying and dead cells bright red fluorescence is generated upon binding to DNA Background fluorescence levels are inherently low with this assay technique because dyes are virtually nonfluorescent before interacting with cells Cell Analysis, Cell Counting and Viability, Cell Counting, Viability, and Cryopreservation, Cell Culture, Cell Viability and Cytotoxicity, Cell Viability, Proliferation and Function Order Info Shipping Condition: Dry Ice
