  • Lumitein™ is a luminescent dye designed for detecting proteins in SDS polyacrylamide (SDS-PAGE) gels. It can also be used to detect proteins in native PAGE gels after an additional SDS incubation step. The stain combines excellent sensitivity, exceptional user-friendliness and compatibility…

  • Hoechst 33258

    Biotium

    For ease of use and safer handling, we offer both Hoechst 33258 and Hoechst 33342 dissolved in H2O at 10 mg/mL. Hoechst dyes are cell membrane-permeant, minor groove binding blue fluorescent DNA stains.

  • DMSO, Anhydrous

    Biotium

    Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.

  • AM1-43

    Biotium

    AM1-43 is a fixable, activity-dependent fluorescent nerve terminal probe. AM1-43 functions similarly similarly to SynaptoGreen C4 (catalog # 70020), but with the additional property of being fixable.

  • 6X GelRed® Prestain Loading Buffers are DNA gel loading buffers containing GelRed® for one-step fluorescent staining and gel loading of DNA.

  • Streptavidin conjugates are prepared from high quality streptavidin biotin binding protein and Biotium’s signature bright and photostable fluorescent CF® dyes, and a selection of other labels.

  • Like Lucifer Yellow CH, Lucifer Yellow Cadaverine can be used as a fixable fluorescent tracer. In addition, the dye can be used to conjugate to carboxylic acid groups.

  • PMA Dye

    Biotium

    PMA (propidium monoazide) is a high affinity photoreactive DNA binding dye invented by scientists at Biotium for viability PCR of bacteria and other microorganisms.

  • RedDot™1 is a far-red cell membrane-permeable nuclear dye similar to Draq5™. The dye is ideal for specifically staining the nuclei of live cells.

  • ADVASEP-7

    Biotium

    ADVASEP-7 is a sulfonated β-cyclodextrin derivative that has been reported to reduce background fluorescence when using SynaptoGreen C4 to stain brain slices.

  • A widely used red fluorescent dye for following synaptic activity by staining synaptic vesicles at the synapse or neuromuscular junctions. When used in combination with the green fluorescent dye SynaptoGreen™, synapses or neuromuscular junctions can be imaged independently in two colors.…
