Cell Based Assays
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™ Dextran, Cascade Blue™, 3000 MW, Anionic, Lysine Fixable
Rigorous methods for removing as much unconjugated dye as practical, followed by assay of dextran conjugates by thin-layer chromatography to help ensure absence of low molecular weight contaminants
Invitrogen™ CellROX™ Deep Red Reagent, for oxidative stress detection
CellROX™ Deep Red Reagent is a novel fluorogenic probe for measuring cellular oxidative stress in both live and fixed cell imaging, with absorption/emission maxima at ∼644/665 nm.
Invitrogen™ Amplex™ Red and Amplex™ UltraRed Reagents
The Amplex Red and UltraRed reagents are fluorogenic substrates for peroxidase. These highly sensitive and stable probes react with H2O2 in the presence of HRP for solution-based assays and ELISAs. Amplex UltraRed is a brighter version of Amplex Red with an improved pH range and sensitivity.
Invitrogen™ HCS LipidTOX™ Red Neutral Lipid Stain, for cellular imaging
High affinity for neutral lipid droplets
Invitrogen™ LIVE/DEAD™ Fixable Near IR (780) Viability Kit, for 633 nm excitation
The LIVE/DEAD Fixable viability kits allow for clear determination of live and dead cells, enabling more precise analysis with both conventional and spectral flow cytometry.
Invitrogen™ Amplex™ Red/UltraRed Stop Reagent
Designed for use with both the Amplex Red and Amplex UltraRed fluorogenic substrates and assay kits
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.
Invitrogen™ Vybrant™ DiI Cell-Labeling Solution
Lipophilic membrane stain that diffuses laterally to stain the entire cell
Invitrogen™ SYTO™ 40 Blue Fluorescent Nucleic Acid Stain - 5 mM Solution in DMSO
For use with fluorescence microscopy and flow cytometry
Invitrogen™ pHrodo™ Dyes for Amine Labeling
Amine-reactive and TFP ester pHrodo dyes enable accurate measurement of cell endocytosis and phagocytosis, with low signal-to-background, for use in live cell assays.
Invitrogen™ CellTracker™ Fluorescent Probes
CellTracker™ is a fluorescent dye well suited for monitoring cell movement or location. After loading into cells, the dye is well retained, allowing for multigenerational tracking of cellular movements.
Molecular Probes™ Annexin V Conjugates for Apoptosis Detection
Detect early stages of apoptosis with Annexin V stand-alone Alexa Fluor, APC, Pacific Blue, PE, FITC, and biotin conjugates using flow cytometry.
