Enzo Life Sciences DAPI (ultra pure) (100mg). CAS: 28718-90-3

DAPI is a fluorescent dye that binds nucleic acids and demonstrates a high affinity for DNA. It is used extensively in fluorescence microscopy, flow cytometry and microplate assays. DAPI is cell permeable and is readily used for detecting both live, dead and fixed cells. DAPI emits in the blue spectral range and is ideal for multiplexed assays inclusive of green-fluorescent molecules like fluorescein and green fluorescent protein (GFP), or red-fluorescent stains like Texas Red. Aside from labeling cell nuclei, DAPI is also used for the detection of mycoplasma or viral DNA in cell cultures. Wavelength Maxima: Excitation 358nm, Emission 461nm Alternative name: 4',6-Diamidino-2-phenylindole . dihydrochloride. Purity: ≥95% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.

Enzo Life Sciences JC-1 (ultra pure) (5mg). CAS: 47729-63-5

JC-1 is widely used for determining mitochondrial membrane potential by flow cytometry, fluorescence microscopy and in microplate-based fluorescent assays. JC-1 accumulates in mitochondria, selectively generating an orange J-aggregate emission profile (590 nm) in healthy cells. However, upon cell injury, as membrane potential decreases, JC-1 monomers are generated, resulting in a shift to green emission (529 nm). The principal advantage of JC-1 relative to other commonly employed fluorescent probes of mitochondrial membrane potential is that it allows for both qualitative visualization, considering the shift from orange to green fluorescence emission, and quantitative detection, considering the fluorescence intensity ratio. Wavelength Maxima: Excitation 515nm, Emission 529nm Alternative name: 5,5',6,6'-Tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide. Purity: ≥95% (TLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.

Enzo Life Sciences LYSO-ID Red detection kit (GFP-CERTIFIED) (500tests)

LYSO-ID Red Lysosomal Detection Kit (GFP-CERTIFIED) is an ideal choice for fluorescence co-localization imaging with GFP-tagged proteins, providing spectrally pure red signal. By contrast, many red-emitting lysosomal probes photoconvert to green fluorescent species or display metachromatic artifacts wherein emission occurs both in the red and green regions of the spectrum, leading to spurious results in GFP co-localization experiments [Freundt et al (2007) Cell Res. 17(11): 956- 958; Nadrigny et al (2007) Biophys J. 93(3):969-980]. The LYSO-ID Red Lysosomal Detection Kit (GFP-CERTIFIED)contains a proprietary acidic organelle-selective dye suitable for staining live cells. The dye is compatible with most fluorescence detection systems, including conventional and confocal fluorescence microscopes, as well as High Content Screening (HCS) platforms. Applications: Fluorescence microscopy, Fluorescent detection .

Enzo Life Sciences ROS-ID Superoxide detection kit (1Kit)

Enzo Life Sciences’ ROS-ID Superoxide detection kit is designed to directly monitor real time superoxide production in live cells using fluorescence microscopy and/or flow cytometry. A major component of the kit, Superoxide Detection Reagent (Orange), is a cell-permeable probe that reacts specifically with superoxide, generating an orange fluorescent product. The kit is not designed to detect reactive peroxide, hydroxyl, peroxynitrite, chlorine or bromine species, as the fluorescent probe included is relatively insensitive to these analytes. Upon staining, the fluorescent product generated can be visualized using a wide-field fluorescence microscope equipped with a standard orange (e.g., 550/620 nm) fluorescent cube, or cytometrically using any flow cytometer equipped with a blue (488 nm) laser. Applications: Flow Cytometry, Fluorescence microscopy, Fluorescent detection, HTS .
