Cellulær Assays

Supplier: Biotium

MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.

TUNEL (terminal deoxynucleotidyl transferase (TdT) mediated dUTP nick-end labeling) is highly selective for the detection of apoptotic cells, but not necrotic cells or cells with DNA strand breaks resulting from irradiation or drug treatment. In this assay, TdT enzyme catalyses the addition of labeled dUTP to the 3’ ends of cleaved DNA fragments. Fluorescent dye-conjugated dUTP can be used for direct detection of fragmented DNA by fluorescence microscopy or flow cytometry.

CellBrite kits are designed to label cell cytoplasmic membranes with a fluorescent membrane dye pre-dissolved as an optimised staining solution. By combining CellBrite membrane stains, it is possible to label multiple cell populations with distinctive colours, a capability useful for the studies of cell-cell interactions.

Neutrophil/Monocyte Respiratory Burst Assay Kit provides PMA, dihydrorhodamine 123, and additional reagents necessary for inducing and quantifying a respiratory burst response in neutrophils and monocytes by flow cytometry. The assay can be performed on whole blood or on cells in various types of cell culture media. Because the assay reagents are not species-specific, this assay can be used in any species or cell type capable of producing a NADPH oxidase-dependent respiratory burst response.

HIF-1α Transcription Factor Assay Kit is a sensitive, non radioactive method for detecting HIF-1α from whole cell lysates.

Supplier: Biotium

This NucView™488 and RedDot™2 Apoptosis and 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. This kit provides a convenient tool for profiling apoptotic and necrotic cell populations by fluorescence microscopy or flow cytometry.

Supplier: Abcam

Exosome Isolation and Analysis Kit - Flow Cytometry, Urine (ab267480) is a simple immunobead assay for isolation/detection of pre-enriched CD63+ human exosomes from biofluids (plasma, urine) or cell culture media.

Supplier: Cayman Chemical

For screening a variety of epigenetic compounds.

Supplier: Biotium

Firefly luciferase is widely used as a transcriptional reporter gene for research and drug screening. The Steady-Luc™ HTS kit can be used with luminescence plate readers without sample injection systems or for high-throughput screening.
