SBFI, AM, cell permeant - Special Packaging Invitrogen™
SBFI is a sodium-sensitive molecule used to estimate Na+ gradients in isolated mitochondria, to measure intracellular NA+ levels, to measure Na+ efflux in cells, and, in combination with other fluorescent indicators used to correlate changes in intracellular Na+ with Ca2+ and Mg2+ concentrations,...
SphingoStrips™ Membranes Invitrogen™
SpingoStrips™ membranes are designed for the identification of proteins possessing phosphoinositide or sphingolipid recognition domains and for analysis of their lipid-binding specificities.
SNARF™-5F 5-(and-6)-Carboxylic Acid Invitrogen™
The cell-impermeant ratiometric pH indicator SNARF®-5F 5-(and-6)-carboxylic acid (pKa of ∼7.2) exhibits a significant pH-dependent emission shift from yellow-orange to deep red fluorescence under acidic and basic conditions, respectively.
The cell-permeant ratiometric pH indicator SNARF®-4F 5-(and-6)-carboxylic acid, acetoxymethyl ester, acetate (pKa of ∼6.4) exhibits a significant pH-dependent emission shift from yellow-orange to deep red fluorescence under acidic and basic conditions, respectively.
Tetramethylrhodamine, methyl ester (TMRM) is a cell-permeant, cationic, red-orange fluorescent dye that is readily sequestered by active mitochondria.
In the Vybrant® Cell Metabolic Assay Kit, nonfluorescent C12-resazurin is reduced to fluorescent C12-resorufin by viable cells; the resulting signal is proportional to the number of cells present. C12-resazurin has better cellular retention than alamarBlue® dye and can be multiplexed with viability...
Vybrant™ DyeCycle™ Orange Stain Invitrogen™
Vybrant® DyeCycle™ Orange Stain is a cell permeable DNA dye that can be used for cell cycle analysis on 488 nm or 532 nm laser lines. • Precise—accurate cell cycle analysis in living cells • Safe—low cytotoxicity for cell sorting and additional live cell experiments • Simple, robust staining...
Vybrant™ Multidrug Resistance Assay Kit Invitrogen™
The Vybrant® Multidrug Resistance Assay Kit provides a rapid and simple method for large-scale screening of MDR inhibitors. This assay uses the fluorogenic dye calcein, AM as a substrate for efflux activity of Pgp.
In the CyQUANT Cytotoxicity Assay Kit, damaged and dying cells release glucose 6-phosphate into surrounding medium. The glucose 6-phosphate is detected by an enzymatic process that leads to the reduction of resazurin into red-fluorescent resorufin.
Amplex™ Red/UltraRed Stop Reagent Invitrogen™
Amplex® Red/UltraRed Stop Reagent is designed for use with the Amplex® Red and Amplex® UltraRed fluorogenic substrates and assay kits. Amplex® Red/UltraRed Stop Reagent provides convenience and control by allowing the fluorescence signal-generating reaction to be terminated at a user-determined time...
Mag-Fura-2, Tetrapotassium Salt, cell impermeant Invitrogen™
Mag-fura-2, tetrapotassium salt is an intracellular magnesium indicator that is ratiometric and UV light-excitable. This water-soluble salt form is useful for intracellular loading by microinjection, infusion from patch pipette or uptake induced by our Influx pinocytic cell-loading reagent (I14402).
MTT is used to assess cell viability as a function of redox potential. Actively respiring cells convert the water-soluble MTT to an insoluble purple formazan. The formazan is then solubilized and its concentration determined by optical density.
