VNIRTM 5(6)-CFDA (mixed isomers) All Products Cell Biology  VNIR 204 Description VNIRTM 5(6)-CFDA (mixed isomers) is a fluorescein-based membrane permeable, non-fluorescent precursor for Carboxy Fluorescein. CFDA staining can be used for cell monitoring by flowcytometry or fluorescence microscopy. This precursor is also used for measuring intracellular pH. This hydrophobic dye is hydrolyzed enzymatically to a hydrophilic, strongly fluorescent carboxyfluorescein. This dye is known to have high retention capability inside the cell. Cat. No. VNIR204 CAS No. 124387-19-5 Molecular weight 460.39 Molecular formula C25H16O9 Appearance White to off-white powder Spectral Property Excitation: 494nm; Emission: 521nm (hydrolyzed product) Purity ≥ 95% (HPLC) Solubility Acetone, DMSO and DMF Storage conditions -20°C (protect from light and moisture) References Please let us know if you publish your research using VNIRTM 5(6)-CFDA.

VNIRTM Nile Red All Products Cell Biology  VNIR 203 Description VNIRTM Nile Red is a highly solvatochromic fluorescent dye used to stain lipid membranes, lipid droplets and hydrophobic regions of proteins. The dye is highly fluorecent in nonpolar/hydrophobic enviroment and non fluorescent in polar enviroments (like water). Nile red exhibits variance in emission wavelength depending the environment. Cat. No.: VNIR203 Concentration 200µM in DMSO Appearance Pink solution Storage conditions -20°C (protect from light) Spectral property Excitation: 552nm, Emission: 636nm [in Methanol] References Please let us know if you publish your research using VNIRTMNile Red.

VNIRTM FDA All Products Cell Biology  VNIR 202 Description VNIRTM FDA is a fluorescein-based membrane permeable, non-fluorescent precursor which upon hydrolysis turns to highly fluorescent fluorescein molecule in live cells. Dead cells cannot accumulate or hydrolyse FDA. Hence this probe can be used differentiate live cells from dead cells. This precursor is commonly used as a cell viability probe and also to measure cell-membrane integrity. Cat. No. VNIR202 CAS No. 596-09-8 Molecular weight 416.38 Molecular Formula C24H16O7 Appearance White to off-white powder Spectral Property Excitation: 492nm; Emission: 515nm, (hydrolysed product) Purity ≥ 95% (HPLC) Solubility Acetone, DMSO and DMF Storage conditions -20°C (protect from light and moisture) References Please let us know if you publish your research using VNIRTM FDA.

Rapid stains of human blood smears All Products Cell Biology  VNIR 201 VNIR DAPI VNIRTM DAPI (4′,6-diamidino-2-phenylindole, dihydrochloride) is a blue emitting fluoroscent stain Having strong binding affinity A-T rich regions of dsDNA. The dye is extensively used in Fluoroscence microscopy and Flow cytometry applications. The dye is generally used for staining fixed cells. They are cell impermeable but they are known to permeate cells at higher concentrations. Cat. No. VNIR201 CAS No. 28718-90-3 Molecular weight 350.25 Molecular formula C16H17Cl2N5 Appearance Clear yellow solution Concentration 200µM in DMSO Spectral property Excitation: 358nm; Emission: 461nm (DNA bound) Storage conditions -20°C (protect from light) References Please let us know if you publish your research using VNIRTM DAPI.
