Biotium Tyramide Amplification Kit with HRP Goat Anti-Rabbit and CF640R Tyramide
Tyramide amplification, sometimes called Catalyzed Reporter Deposition (CARD), is an enzyme-mediated detection method that uses the catalytic activity of horseradish peroxidase (HRP) to generate high density labeling of a target protein or nucleic acid sequence in situ. The tyramide amplification method has been reported to increase the sensitivity by up to 100-fold compared to the conventional avidin-biotinylated complex procedure. The kit contains HRP goat anti-rabbit CF640R dye tyramide. The dye has an excitation/emission of 642/662 nm. The kit contains sufficient reagent for 50-150 slides.
Biotium CF350 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. UV-excitable blue fluorescent CF350 dye has excitation/emission at 347/448 nm.

Enzo Life Sciences DilC12(3) perchlorate (ultra pure) (100mg). CAS: 75664-01-6
DiI, DiO, DiD and DiR dyes are a family of lipophilic fluorescent stains for labeling membranes and other hydrophobic structures. The fluorescence of these environmentsensitive dyes is greatly enhanced when incorporated into membranes or bound to lipophilic biomolecules such as proteins although they are weakly fluorescent in water. Once applied to cells, these dyes diffuse laterally within the cellular plasma membranes, resulting in even staining of the entire cell at their optimal concentrations. DiIC12(3) is a lipophilic neuronal tracer that is commonly used for labeling neuronal projections as well as lipid bilayers in other cell types, particularly endothelial cells. Wavelength Maxima: Excitation 549nm, Emission 565nm. Alternative name: 1,1'-Didodecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate. Purity: ≥98% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
Enzo Life Sciences Dihydrorhodamine 123 (ultra pure) (10mg). CAS: 109244-58-8
Dihydrorhodamine 123 is a widely utilized probe for detection of intracellular reactive oxygen species (ROS) such as peroxide, hypochlorous acid and peroxynitrite. It is readily oxidized into rhodamine 123, which exhibits a spectral profile similar to that of FITC. In combination with other fluorescent probes (such as surface receptor-targeted fluorescent antibodies, the cell viability probe propidium iodide, or fluorescent calcium indicators) dihydrorhodamine 123 can be used for multiparametric cell measurements. Wavelength Maxima: Excitation 507nm, Emission 529nm Alternative name: 2-(3,6-Diamino-9H-xanthene-9-yl)-benzoic acid methyl ester. Purity: ≥95% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.

Sulfo-NHS-LC-Biotin sodium is a water-soluble, amine-reactive sulfo-NHS ester of biotin with a long-chain spacer (LC) that enables efficient labeling of primary amines on proteins and other biomolecules. It is formulated as the sodium salt to improve aqueous solubility and is suited for selective cell-surface biotinylation, detection, and affinity capture applications.
- Amine-reactive sulfo-NHS ester for efficient biotinylation.
- Long-chain spacer reduces steric hindrance and preserves biomolecule function.
- Water-soluble sodium salt suitable for aqueous labeling of surface proteins.
- Limited membrane permeability for selective cell-surface labeling.
- High purity and well-characterized for reproducible results.
- Soluble in DMSO (approx. 175 mg/mL); store sealed and away from moisture.
