Flow Cytometry

A sensitive, safe and cost-effective high-throughput homogeneous assay of cell viability by fluorescence or absorbance measurement.

Thiazole Red, also known as TO-PRO®-3, is a cell-impermeant, high-affinity far-red nucleic acid stain.

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

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.

Label your antibody with one of our CF® Dyes specialized for STORM super-resolution microscopy. Labeling takes just 30 minutes without a purification step, and yields an antibody conjugate with a low degree of labeling optimal for STORM.

Oxazole Blue, also known as PO-PRO™-1, is a blue-fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

Recombinant human Annexin V expressed from E. coli as a single, non-glycosylated polypeptide chain. The protein is available with no tag or a C-terminal 6X His tag.

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

7-AAD (7-aminoactinomycin D) is a membrane-impermeant fluorescent DNA binding dye that is useful for live/dead discrimination and cell cycle profiling by flow cytometry.

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.

Ac-DEVD-CHO is a synthetic tetrapeptide competitive inhibitor for Caspase-3/7, and contains the amino acid sequence of the PARP cleavage site. Ac-DEVD-CHO can be used to inhibit Caspase-3/7 activity in apoptotic cells, and to study events downstream of Caspase-3/7 activation.

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.

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.

Label your IgG antibody with one of our superior CF® Dyes in as little as 15 minutes without a purification step. Labeling tolerates many common buffer components including BSA and ascites.

Label your IgM antibody with one of our superior CF® Dyes in 15-30 minutes without a purification step.
