This product is prepared by labeling highly cross-adsorbed goat anti-human IgG (H+L) with CF®583R dye. To minimize cross-reactivity, the antibody has been adsorbed against bovine, horse, and mouse serum.
L-NIO ( N 5 -(1-Iminoethyl)-L-ornithine, dihydrochloride) is a potent, irreversible inhibitor of neutrophil nitric oxide synthase. White solid soluble in water Store desiccated at -20°C C7H17Cl2N3O2 MW: 246.1 [36889-13-1]
The Yeast Viability Staining Kit is used to differentiate live and dead cells in yeast. It has two components: ConA, which stains all cells, and Live-or-Dye™, which stains only dead cells.
This product is prepared by labeling highly cross-adsorbed goat anti-human IgG (H+L) with CF®647 dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent...
SynaptoRed™ C1 is similar to the widely used red fluorescent nerve terminal dye SynaptoRed™ C2 (also called FM4-64) except that the lipophilic tail of SynaptoRed™ C1 is one carbon shorter than that of the SynaptoRed™ C2. Thus, SynaptoRed™ C1 is expected to have a faster off-rate compared to...
SynaptoRed™ C2M is a red fluorescent probe used to follow synaptic vesicles. SynaptoRed™ C2M is slightly more water soluble than SynaptoRed™ C2 (equivalent to FM®4-64). FM is a registered trademark of Thermo Fisher Scientific.
CPM (full name: 7-diethylamino-3-(4'-maleimidylphenyl)-4-methylcoumarin) is probably the most widely used blue fluorescent thiol-reactive dye. This maleimide derivative of coumarin is essentially nonfluorescent until it reacts with thiols, making it possible to quantify thiols without a separation...
