Biotium Hydroxystilbamidine, 4% in H2O

Hydroxystilbamidine (also called Fluoro-Gold) has been used extensively as a retrograde tracer for neurons and also a histochemical stain. Fluoro-Gold can undergo retrograde axonal transport, it shows extensive filling of dendrites, and has a high resistance to fading. The 4% solution in deionized H2O is a convenient, ready-to-use form. If desired, the solution can be diluted to a lower concentration. For most applications, the typically dye concentration is 2% to 4%. We also sell hydroxystilbamidine in solid form. Properties: Ex/Em = 361/536 nm; Store at 4°C and protect from light; C18H24N4O7S2; MWt: 473; [223769-64-0].Fluoro-Gold is a trademark of Fluorochrome, LLC.

Biotium DPA

Dipicrylamine (DPA) is a nonfluorescent anionic membrane dye. With its absorbance in the blue region of the visible spectrum, DPA can be used as a FRET quencher for a variety of fluorescent donor dyes. When applied to cells, DPA localizes at the interface of cytoplasmic membrane and aqueous phase in a manner sensitive to membrane potential change. A recent application of DPA is to measure cell membrane potential change by combining with the fluorescent donor dye DiOC16. The DiO/DPA system has been reported to produce a fluorescence signal change of >56% in HEK-293 cells and >25% in neuronal cultures and brain slices per 100 mV membrane potential change. Please also see the DiO/DPA Membrane Potential Detection Kit. Properties: Yellow solid soluble in DMSO at >30mg/mL; Abs. (MeOH) = 406 nm; Store at 4°C; MWt: 439.21; [131-73-7]

Biotium Nonyl Acridine Orange (NAO)

NAO is a mitochondrial dye whose staining is not dependent on mitochondrial membrane potential, unlike JC-1 and Rhodamine 123. NAO has been used to study multidrug resistance and to measure changes in mitochondrial mass during apoptosis.Properties: Ex/Em (MeOH) = 495/522nm; e (MeOH) = 63,000; Orange solid soluble in DMSO or DMF; Store at 4°C and protect from light, especially in solution; C26H38BrN3; MW: 473; [75168-11-5]
