Metabolic Activity

Marker Gene Technologies, Inc. offers several alternatives for measuring the metabolic status of cells in microplate or microscopy formats. Metabolic activity serves as a key monitor of cell viability, health and cell number. Choose from assays for oxidoreductases with the classic MTT system, esterases with either fluorescein diacetate or resorufin acetate, or ubiquitous β-glucosidase activity using resorufin β-D-glucopyranoside. We also offer a collection of patented, red-shifted luciferase assays that parallel changes in ATP levels in cell extracts

  3. Resorufin acetate

    Resorufin acetate

    $81.59

    Common long-wavelength esterase substrate, useful in cell viability assays, or for high throughput screening of esterase activity in a live cell format. Learn More
  4. MarkerGene™ Long Wavelength Fluorescent Lipase Assay Kit

    MarkerGene™ Long Wavelength Fluorescent Lipase Assay Kit

    $280.19

    This kit allows fast and easy measurement of lipase activity in vitro, in cell preparations or in vivo using the long wavelength substrate resorufin oleate. Learn More
  5. MarkerGene™ Non-Radioactive Cell Proliferation Assay Kit

    MarkerGene™ Non-Radioactive Cell Proliferation Assay Kit

    $289.51

    This kit uses the highly accurate and widely used MTT dye to measure cell viability in a microtiterplate format. Learn More
  6. Fluo-3 AM

    Fluo-3 AM

    $316.15

    Cell permeable fluorescent indicator for intracellular calcium. It is non-fluorescent until hydrolyzed intracellularly. Learn More
  7. Calcein Blue AM acetate

    Calcein Blue AM acetate

    $99.00

    Calcein Blue AM acetate is a cell-permeant, blue fluorescent viability probe. It can be used with other probes to quickly and easily measure the total number of live versus dead cells. It's blue emission won't overlap with other probes having green fluorescence, like GFP. Learn More
