STEMCELL Technologies GloCell™ Fixable Viability Dye Violet 510, Size: 100 Tests
GloCell™ Fixable Viability Dye Violet 510 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Violet 510 is excited by the violet laser at 405 nm and it has a fluorescence emission maximum of 510 nm that can be detected using the 525/50 band pass filter used to detect AmCyan.
STEMCELL Technologies GloCell™ Fixable Viability Dye Red 780, Size: 500 Tests
GloCell™ Fixable Viability Dye Red 780 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Red 780 is excited by the red laser at 633 nm and it has a fluorescence emission maximum of 780 nm that can be detected using the 780/60 band pass filter used to detect APC-Cy7.
Aat Bioquest Cyanine 5 azide [equivalent to Cy5® azide]
A variety of cyanine 5 ( Cy5®) dyes has been used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. They are widely used for labeling peptides, proteins and oligos etc.
Biotium MemBrite™ Fix 488/515 Cell Surface Staining Kit, 500 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 kit has reagents sufficient for 500 labeling reactions. The kit contains 5 vials of MemBrite™ Fix 488/515. Each vial is sufficient for 20 uL of 1000X dye after DMSO reconstitution.
Biotium Mix-n-Stain™ CF594 Small Ligand Labeling Kit
Mix-n-Stain™ Small Ligand Labeling Kits are designed for rapid labeling of low molecular weight (MW 150 -5000) ligands without a purification step. Suitable ligands or substrates include SNAP-tag, CLIP-tag™ and HaloTag ligand derivatives that have an aliphatic amine. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Deep-red fluorescent CF594 dye has excitation/emission at 593/614 nm. It is suitable for labeling ligands for cell surface staining.
Biotium CF660C, Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. 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 CF660C dye has excitation/emission at 667/685 nm.
Biotium CF568 Biocytin
Fluorescent biocytin conjugates are cell-impermeant, fixable polar tracers with biotin and an aldehyde-fixable primary amine groups. Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.
Biotium CF405M Protein Labeling Kit , 3x(1mg) labelings
This kit contains everything you need to label antibodies or other proteins with a fluorescent CF dye succinimidyl ester (CF dye SE). Each kit contains reagents for three labeling reactions of up to 1 mg protein per reaction. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Blue fluorescent CF405M dye has excitation/emission at 408/452 nm.
Biotium Furaptra, AM Ester, 20x50ug
Furaptra, AM ester is a membrane-permeant form of Furaptra (Mag-Fura-2). The indicator is loaded into cells via simple incubation, where it is cleaved by cytoplasmic esterases to release Mag-Fura-2. Properties: Light yellow solid soluble in DMSO; Store at -20°C and protect from light; C30H30N2O19; MW: 723
Biotium CF770R Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. 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/near-IR fluorescent CF770R dye has excitation/emission at 770/701 nm.
