Together, cell viability and cell toxicity assays are important tools for assessing cellular responses to experimental compounds of interest. endstream

Cell viability assays are used to determine the overall health of cells, optimize culture or experimental conditions, and to measure cell survival following treatment with compounds, such as during a drug screen. Secondary necrosis commonly occurs in cell populations undergoing extensive apoptosis. Apoptotic stimuli trigger cytochrome c translocation from the mitochondria to the cytosol.

Our general aim was to study how C2C12 myoblast behave within different hydrogels in terms of viability, apoptosis and membrane integrity.

Cell debris is packaged into apoptotic bodies which are then engulfed and digested by phagocytes. Merci d'avoir vérifié votre adresse email. This product is available through the Promega Helix onsite stocking program.

The Cell Health Assay is a fluorescence-based assay used for live/dead cell counting that is amenable to fluorescence microscopy and flow cytometry analyses wherein live cells are detected by the conversion of calcein-AM to calcein and dead cells by uptake of propidium iodide.

DNA strand breaks and DNA fragmentation are characteristic of late-stage apoptosis and can be detected using terminal deoxynucleotidyl transferase (TdT) dUTP nick end labeling (TUNEL assay) to quantify the number of apoptotic cells within a population via IF, IHC, plate reader, or flow cytometry. Promega CytoTox-ONE™ Homogeneous Membrane Integrity Assay A fast homogeneous, fluorometric method for estimating the number of non-viable cells present in multiwell plates. The assay rapidly measures the release of lactate dehydrogenase (LDH) from cells with a damaged membrane.
The CytoTox-ONE™ Reagent mix does not damage healthy cells; therefore, researchers can measure released LDH directly in assay wells containing a mixed population of viable and damaged cells.
Save time by setting up the assay in a cell culture plate; this eliminates the sample transfer step common in many LDH assays. Healthy cells actively proliferate whereas growth-arrested, senescent, and dead or dying cells do not. The XTT cell viability assay is an alternative to the MTT assay which yields a formazan product that is soluble in aqueous solutions, and thus does not require an additional solubilization step.

The CytoTox-ONE Assay rapidly measures the release of lactate dehydrogenase (LDH) from cells with a damaged membrane. Cell toxicity refers to the ability of a substance to damage or kill cells.

A classic morphological feature of apoptotic cells is the condensation of nuclear chromatin from a heterogeneous to compact state. This pathway is also activated by pro-inflammatory signaling and ischemic injury. Measuring leakage of components from the cytoplasm into the surrounding culture medium has been widely accepted as a valid method to estimate the number of nonviable cells.
