  • AccuOrange™ Protein Quantitation Kit

    Biotium

    AccuOrange™ Protein Quantitation Kit is a highly sensitive fluorescence-based assay for quantitating purified protein samples in 96-well format (excitation/emission = 480/598 nm). The detection range of the assay is 0.1-15 ug/mL protein.

  • Resazurin Cell Viability Assay Kit

    Biotium

    Resazurin Cell Viability Assay offers a simple, rapid, reliable, sensitive, safe and cost-effective measurement of cell viability. This kit performs at least as well as other commercial resazurin-based cell proliferation assay kits such as alamarBlue® or CellTiter-Blue®.

  • ATP-Glo™ Bioluminometric Cell Viability Assay

    Biotium

    ATP-Glo™ Bioluminometric Cell Viability Assay offers a highly sensitive assay for quantifying ATP. The homogeneous assay procedure involves a single addition of ATP-Glo™ Detection Cocktail directly to cells cultured in a serum-supplemented medium.

  • Apoptotic, Necrotic, and Healthy Cells Quantification Kit

    Biotium

    The kit allows simultaneous quantification of apoptotic (green), necrotic (red) and all cells (blue) within the same cell population by flow cytometry or fluorescence microscopy.

  • XTT Cell Viability Assay Kit

    Biotium

    XTT Cell Viability Assay Kit provides a simple method for determining live cell numbers using standard photometric microplate readers. Determination of live cell numbers is often used to assess the rate of cell proliferation and to screen cytotoxic agents.

  • Dual Apoptosis Assay with NucView® 488 Caspase-3 Substrate & Annexin V

    Biotium

    These kits provides two apoptosis markers, our novel NucView® 488 Caspase-3 Substrate and Annexin V conjugated with your choice of red or far-red dye. The kit is used for studying two important apoptosis events, caspase-3 activation and phosphatidylserine (PS) translocation.

  • Steady-Luc™ Firefly HTS Assay Kit

    Biotium

    Firefly luciferase is widely used as a reporter for studying gene regulation and function, and for pharmaceutical screening. Biotium’s Steady-Luc™ HTS assay system is a homogeneous firefly luciferase reporter gene assay kit with a half-life of about 3 hours for the quantification of…

  • JC-1 Mitochondrial Membrane Potential Detection Kit

    Biotium

    JC-1 Mitochondrial Membrane Potential Detection Kit is used to measure mitochondrial membrane potential changes in cells.

  • Viability/Cytotoxicity Assay Kit for Bacteria Live and Dead Cells

    Biotium

    This kit provides a two-color fluorescence staining on both live bacteria (green) and dead bacteria (red) using two probes DMAO and EthD-III.

  • NucView® 488 Caspase-3 Assay Kit for Live Cells

    Biotium

    NucView® 488 Caspase-3 substrate is a novel cell membrane-permeable fluorogenic caspase substrate designed for detecting caspase-3 activity within live cells in real time.

  • CellBrite™ Cytoplasmic Membrane Labeling Kits

    Biotium

    CellBrite™ Cytoplasmic Membrane Labeling Kits are designed to label cell cytoplasmic membranes with fluorescent dyes, available in blue, green, orange, and red. The labeling is stable and nontoxic, suitable for long-term tracking of cells.

  • Caspase-3 DEVD-R110 Fluorometric HTS Assay Kit

    Biotium

    Caspase-3 DEVD-R110 Fluorometric HTS Assay Kit is specifically designed for HTS-based assays. The kit provides a homogenous assay system for fast and highly sensitive detection of caspase-3 activity by fluorescence in enzymatic reaction or mammalian cells.

  • Viability/Cytotoxicity Assay Kit for Animal Live & Dead Cells

    Biotium

    The Viability/Cytotoxicity Assay Kit for Animal Live & Dead Cells provides green/red fluorescent staining of live and dead cells, respectively. The assay employs two probes that detect intracellular esterase activity in live cells and compromised plasma membrane integrity in dead cells.

  • ViaFluor® SE Cell Proliferation Kits

    Biotium

    ViaFluor® SE Cell Proliferation Kits use amine-reactive dyes to covalently label the cell cytoplasm, and are used to monitor cell division by flow cytometry. The dyes also can be used to stably label cells to image cell morphology, or to track cell populations in mixed co-culture experiments.…

  • Caspase-3 DEVD-R110 Fluorometric and Colorimetric Assay Kit

    Biotium

    Caspase-3 is an active cell-death protease involved in the execution phase of apoptosis, during which cells undergo morphological changes such as DNA fragmentation, chromatin condensation and apoptotic body formation.

  • Apoptosis and Necrosis Quantification Kit

    Biotium

    The Apoptosis & Necrosis Quantification Kit provides a convenient assay for quantifying apoptotic (green) and necrotic (red) cells within the same cell population by flow cytometry or fluorescence microscopy.

  • TUNEL Assay Apoptosis Detection Kit

    Biotium

    The CF® dye TUNEL Assay Apoptosis Detection Kit employs dUTP conjugated to the exceptionally bright and photostable fluorescent dyes, for single step fluorescent TUNEL labeling of fixed cells or tissues for analysis by fluorescence microscopy or flow cytometry.

  • NucView® 488 and RedDot™ 2 Apoptosis and Necrosis Kit

    Biotium

    NucView®488 and RedDot™2 Apoptosis/Necrosis Assay Kit contains NucView®488 Caspase-3 Substrate for detection of caspase-3/7 activity. The far-red dead-cell stain RedDot™2 is included for staining necrotic and late apoptotic cells that have compromised plasma membrane integrity.
