Oxazole Blue Homodimer, also know as POPO-1, is a cell-impermeant, high-affinity carbocyanine monomeric nucleic acid stain that is essentially nonfluorescent in the absence of nucleic acids but exhibits excitation/emission maxima 435/455 nm when bound to nucleic acids.

Fast Probe Master Mix is formulated for conducting real-time PCR using an oligo-based probe, such as a TaqMan® probe, a MGB probe or an AllGlo™ probe. The master mix contains buffer, dNTPs, MgCl2 and our superior hotstart enzyme Cheetah™ Taq.

AM4-64 is a fixable, activity-dependent fluorescent nerve terminal probe. AM4-64 functions similarly similarly as SynaptoRed™ C2 (equivalent to FM®4-64), but with the additional property of being fixable. Thus, AM4-64 is a useful tool for synapse studies where subsequent fluorescent immunochemistry...

This product is prepared by labeling highly cross-adsorbed goat anti-rabbit IgG (H+L) with CF®543 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. Orange fluorescent...

Forget-Me-Not™ EvaGreen® qPCR Master Mix is a high performance, hot-start EvaGreen® dye-based master mix for use in real time PCR applications and DNA melt curve analysis. Forget-Me-Not™ master mix has a light blue master mix color which helps prevent pipetting mistakes, saving time and reagents....

Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF®594 to stain the surface of gram-positive cells with red fluorescence. CF®594 is spectrally...

This product is prepared by labeling highly cross-adsorbed goat anti-rabbit IgG (H+L) with biotin. To minimize cross-reactivity, the antibody has been adsorbed against human, mouse, and rat serum.
