Apoptosis & Viability Assays

Thiazole red homodimer (TRhD), also known as TOTO®-3, is a cell-impermeant, high-affinity, far-red fluorogenic nucleic acid stain.

Oxazole Yellow, also known as YO-PRO®-1, is a green-fluorescent, cell-impermeant nucleic acid stain that can be used as a early marker of apoptosis.

TO Iodide, also known as TO-PRO®-1, is a green fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

A cell-permeable dye that exhibits enhanced fluorescence upon binding to amyloid fibrils, and has been used in histology and for protein characterization.

Congo Red has been used in microscopy for staining elastic fibers and bacteria. Amyloid protein, an abnormal protein aggregate associated with various pathologies, is commonly detected in tissue with Congo Red.

A red fluorescent dye to covalently label dead cells, allowing cells with permeable plasma membranes to be detected in flow cytometry and microscopy.

Far-red fluorescent probe with high affinity for Aβ plaques/aggregates, that can be used for fluorescent staining of brain sections and in vivo detection of Aβ_1-42 aggregates in small animals.

Homogeneous, no wash assay for detection of caspase-3/7 activity with green fluorescence and dead cell staining with far-red fluorescence, for fluorescence microscopy or flow cytometry.

This kit provides two-color fluorescence staining of both live bacteria (green) and dead bacteria (red) using two DNA dyes, DMAO and EthD-III.

Ac-DEVD-AMC is a fluorogenic substrate for caspase 3 and can be used to continuously measure the activity of caspase-3 in cell extracts, using a fluorometer or fluorescence microplate reader. For real-time detection of caspase-3 activity in intact cells, see our novel NucView®488 Caspase-3 Assay Kit.

Concentrated buffer used for Annexin V staining of cells to monitor apoptosis.

PathoGreen™ Histofluorescent Stain is an anionic green fluorescent dye functionally similar to Fluoro-Jade dyes. These dyes stain degenerating neurons and their processes after exposure to a variety of neurotoxic insults in brain sections and cultured neurons.

A far-red cell membrane-impermeant nuclear dye with greater nuclear specificity than Draq7™. Ideal for fixed cell nuclear counterstaining with minimal cytoplasmic RNA staining.

A red fluorescent dead cell stain for bacteria and mammalian cells

A red fluorescent dead cell stain for bacteria and mammalian cells that is brighter than Ethidium Homodimer I.

A convenient assay for quantifying apoptotic (green), necrotic (red), and total (blue) cells within the same cell population by flow cytometry or fluorescence microscopy.
