    TOOLS Cell Counting (CCK-8) kit

    TOOLS Cell Counting (CCK-8) kit is a ready-to-use solution without premixing of components. Cell Counting Kit-8, being nonradioactive, allows sensitive colorimetric assays for the determination of the number of viable cells in cell proliferation and cytotoxicity assays. WST-8 is reduced by dehydrogenases in cells to give a yellow colored product (formazan), which is soluble in the tissue culture medium. The amount of the formazan dye generated by the activity of dehydrogenases in cells is directly proportional to the number of living cells. The detection sensitivity of CCK-8 is higher than other tetrazolium salts such as MTT, XTT, MTS or WST-1.

    MTT Cell Proliferation and Cytotoxicity Assay Kit

    MTT Cell Proliferation Assay Kit provides a simple method for determination of cell number using standard microplate absorbance readers. Determination of cell growth rates is widely used in the testing of drug action, cytotoxic agents and screening other biologically active compounds. Several methods can be used for such determinations, but indirect approaches using fluorescent or chromogenic indicators provide the most rapid and large-scale assays.Among such procedures, the MTT assay developed by Mossman1 is still among one of the most versatile and popular assays. The MTT assay involves the conversion of the water-soluble MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) to an insoluble formazan.2-4 The formazan is then solubilized, and the concentration determined by optical density at 570 nm. The result is a sensitive assay with excellent linearity up to approximately 96 cells per well.

  • WST-1 Cell Proliferation and Cytotoxicity Assay Kit

    WST-1 Cell Proliferation and Cytotoxicity Assay Kit

    A main application allows assessing the viability (cell counting) and the proliferation of cells (cell culture assays). It can also be used to determine cytotoxicity of potential medicinal agents and toxic materials since those agents would stimulate or inhibit cell viability and growth. The kit components are sufficient for performing up to 100 or 500 assays.
