Biotium XTT Cell Viability Assay Kit (1000 Assays)
The 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. XTT is a tetrazolium derivative. Similar to MTT, XTT measures cell viability based on the activity of mitochondrial enzymes in live cells that reduce XTT and are inactivated shortly after cell death. Unlike MTT, XTT is reduced to a highly water-soluble orange-colored product instead of the insoluble formazan from MTT, thus eliminating the solubilization step required for the MTT assay. The amount of water-soluble product generated from XTT reduction is proportional to the number of living cells in the sample and can be photometrically quantified at 475 nm. Continuous color development permits measurements at multiple time points for extended detection range.

CHEMOMETEC Solution 17 Blood Lysis Buffer, 25ml
Solution 17 – Blood Lysis Buffer is used for sample preparation prior to enumerating dead and viable leukocytes in blood samples, such as EDTA-treated whole blood, buffy coats, and bone marrow. The Blood Lysis Buffer is designed for preferential lysis of erythrocytes and simultaneous staining of leukocytes in blood samples. The solution contains two different dyes: acridine orange stain all nucleated cells and 4’,6-diamidino-2-phenylindole (DAPI) stains nonviable cells only. Storage: 2 – 7°C. *All ChemoMetec products are shipped at ambient temperature. Function and quality of products have been validated to ensure shipment at ambient temperature (14 days) does not have any influence on products. At receipt, products should be stored accord to the defined storage conditions available on the package insert.

AKADEUM LIFE SCIENCES INC Akadeum DEAD CELL REMOVAL Microbubble Kit
The Dead Cell Removal Microbubble Kit is designed to deplete apoptotic cells from a variety of biological samples. During apoptosis, phosphatidylserine (PS) – a phospholipid normally found on the inner surface of the plasma membrane – is redistributed to the extracellular surface. The relocation of PS to the outer surface of the cell membrane provides an effective target for differentiating dead cells from viable cells within a biological sample. The Dead Cell Removal Kit utilizes BACS™ Microbubbles coated with Annexin V, a PS binding molecule, to capture and float dead cells away. How it Works: The Dead Cell Removal Microbubble Kit are mixed into the sample where they bind to dead and dying cells. Following a centrifugation step, the microbubbles and dead cells are aspirated away while enriched cells are left healthy, untouched, and ready for a wide variety of applications such as single-cell techniques, flow sorting, and cell culturing. Capacity: 1mL
