Cell Based Assays
Invitrogen™ LIVE/DEAD™ Cell Imaging Kit (488/570)
Sensitive two-color fluorescence cell viability assay optimized for FITC and Texas Red™ filters
Invitrogen™ Calcein AM, Cell-permeant Green and Blue Dyes
Calcein AM is a cell-permeant dye that can be used to determine cell viability in most eukaryotic cells. In live cells, the non-fluorescent Calcein AM is converted to green or blue fluorescent Calcein, after acetoxymethyl ester hydrolysis by intracellular esterases.
Invitrogen™ SYTO™ Green Fluorescent Nucleic Acid Stains
SYTO Green Fluorescent Nucleic Acid Stains exhibit bright, green fluorescence upon binding to nucleic acids. These dyes are cell-permeant and can be used to stain RNA and DNA in live cells, dead cells, and bacteria.
Invitrogen™ CellMask™ Plasma Membrane Stains
Invitrogen CellMask™ plasma membrane stains enable fast and uniform labeling of the plasma membrane in almost all cell types. These stains work rapidly and can be detected using standard microscope filter sets with any imaging instrument.
Invitrogen™ PrestoBlue™ and PrestoBlue™ HS Cell Viability Reagents
Monitor cell proliferation and viability with the resazurin-based PrestoBlue and PrestoBlue HS cell viability reagents. These nontoxic and cell permeable reagents quantitatively measure cell viability in as little as 10 minutes using absorbance- or fluorescence-based microplate readers.
Molecular Probes™ LIVE/DEAD™ Fixable Aqua Dead Cell Stain Kit, for 405 nm excitation
The LIVE/DEAD™ Fixable Aqua Dead Cell Stain Kit is used to determine the viability of cells prior to the fixation and permeabilization required for intracellular antibody staining, or prior to elimination of biohazardous materials using formaldehyde fixation.
Invitrogen™ Amplex™ Red Hydrogen Peroxide/Peroxidase Assay Kit
Sensitive, one-step assay to detect hydrogen peroxide (H2O2) or peroxidase activity
Invitrogen™ LIVE/DEAD™ Viability/Cytotoxicity Kit, for mammalian cells
Useful with a variety of fluorescence-detection methodologies
Invitrogen™ DAPI and Hoechst Nucleic Acid Stains
DAPI and Hoechst are classic popular nuclear counterstains for use in all fluorescent cell and tissue techniques. The blue fluorescence is vivid contrast to green, yellow, orange, red, far red and NIR fluorescent probes and labels.
Invitrogen™ CellROX™ Green Reagent, for oxidative stress detection
Novel fluorogenic probe for measuring oxidative stress in live cells
Invitrogen™ CyQUANT™ MTT and XTT Cell Viability Assays
CyQUANT MTT and XTT Cell Viability assays are colorimetric microplate assays for accurate assessment of cell health, proliferation, and cytotoxicity. CyQUANT MTT is a well-established assay, while CyQUANT XTT offers improved performance and continuous measurement without cell lysis or solubilization.
Molecular Probes™ Fluo-4, AM, cell permeant
Fluo-4 is an analog of fluo-3 with the two chlorine substituents replaced by fluorines, which results in increased fluorescence excitation at 488 nm and consequently higher fluorescence signal levels.
Invitrogen™ CyQUANT™ Cell Proliferation Assays
CyQUANT cell proliferation assays are fast and highly sensitive fluorescence methods for counting cells to assess cell growth and cytotoxicity in microplate format. These assays use fluorescent nucleic-acid-binding dyes to measure cell number based on DNA content.
Molecular Probes™ Dead Cell Apoptosis Kits with Annexin V for Flow Cytometry
Assess cell viability with Dead Cell Apoptosis kits with Annexin V and conjugated fluorescent dyes such as Alexa Fluor 488, FITC, PI, PE, APC, and SYTOX Green.
Invitrogen™ Propidium Iodide Ready Flow™ Reagent
Propidium Iodide Ready Flow™ Reagent is a bright, easy-to-use nucleic acid stain for distinguishing dead cells from live cells in flow cytometry assays.
