Biotium LysoView™ 633, 100uL
LysoView™ dyes are fluorescent stains for imaging lysosome localization and morphology in live cells. The dyes accumulate in the low pH environment of the lysosomes, resulting in highly specific lysosomal staining without the need for a wash step. Far-red fluorescent LysoView™ 633 exhibits pH-sensitive fluorescence (Ex/Em 634/659 nm at pH ≤5), further enhancing the specificity of staining.
Biotium MemBrite™ Fix 488/515 Cell Surface Staining Kit, 100 Reactions
MemBrite™ Fix Cell Surface Staining Kits are designed for covalently staining the surface of live cells to conveniently visualize cell boundaries in immunofluorescence experiments. MemBrite™ Fix are new covalent cell surface stains that react irreversibly with cell surface proteins for staining that can withstand formaldehyde or alcohol fixation, and detergent permeabilization. Unlike lectins such as WGA, which bind specific targets that may vary between cell types, MemBrite™ Fix dyes react widely with cell surface proteins. MemBrite™ Fix staining is rapid and non-toxic to cells, and because MemBrite™ Fix dyes are highly water soluble, they stain cells much more evenly than traditional lipophilic membrane dyes like DiO, DiI, PKH, Vybrant, or CellMask™. This trial size kit has reagents sufficient for 100 labeling reactions. The kit contains 1 vial of MemBrite™ Fix 488/515 that is sufficient for 20 uL of 1000X dye after DMSO reconstitution.
Biotium ViaFluor 405 Live Cell Microtubule Stain, Trial Size
ViaFluor™ 405 is a blue fluorescent taxol probe with excitation/emission at 408/452 nm that allows fluorescent staining of microtubules in living cells for detection in the DAPI channel. Supplied at 1000X in DMSO, with a vial of 100 mM verapamil, which can enhance staining in some cell types.
Biotium Lucifer Yellow CH Potassium Salt
Lucifer Yellow CH potassium salt (LY CH potassium salt) is a widely used polar molecular tracer for studying neuronal morphology. The fluorescent molecule contains a carbohydrazide that allow the molecule to be aldehyde-fixable. Properties: Ex/ Em = 428/536 nm; Yellow solid soluble in water; Store at 4°C and protect from light; C13H9K2N5O9S2; MW: 522; [71206-95-6]
