Dyes and Labeling Reagents

This category comprises chemicals for permanent and temporary labeling of organelles, proteins, and other molecules. For example, this includes the covalent linkage of a target protein, such as an antibody, with a fluorescent dye/fluorophore, allowing detection of the target protein in microscopic experiments. For the purpose of detection, proteins can also be coupled with reporter enzymes (e.g. HRP) or radioactive isotopes. To facilitate the purification of a target protein, biotinylation followed by streptavidine affinity binding has proven to be effective.

5-dR110 [5-Carboxy-4,7-dichlororhodamine 110]
5-dR110 [5-Carboxy-4,7-dichlororhodamine 110]

Item number: ABD-315

Compared to fluorescein labeling reagents such as FITC and FAM, 5-dR110 [5-carboxy-4,7-dichlororhodamine 110] reagents give more photostable and pH-independent bioconjugates that have the absorption maximum around the preferred 488 nm excitation wavelength. They are photostable alternative reagents superior to FITC...

5-ROX, SE [5-Carboxy-X-rhodamine, succinimidyl ester] *CAS 209734-74-7*
5-ROX, SE [5-Carboxy-X-rhodamine, succinimidyl ester]...

Item number: ABD-391

Single isomers of ROX are increasingly preferred for labeling peptides and nucleotides because they give better resolution in HPLC purifications that are often required in bioconjugations. Variable ratios of the 5- and 6-isomers often cause complications in the interpretation of labeling results and assay...

Sunnyvale Red(TM) SE *Superior 6-ROX Replacement*
Sunnyvale Red(TM) SE *Superior 6-ROX Replacement*

Item number: ABD-394

Although ROX dyes have strong fluorescence they are notoriously unstable. Some commercial samples only have a few months shelf life. Compared to 6-ROX labeling compounds our Sunnyvale Red(TM) dyes have greatly enhanced stability while they have essentially identical spectral properties to those of 6-ROX when...

Item number: ABD-399

6-ROX, SE is the other purified single isomer of 5(6)-ROX, SE. 6-ROX is predominately used for labeling nucleotides and sequencing nucleic acids. Compared to other rhodamines, ROX is very unstable. Cautions must be exercised to prevent the deterioration during storage.

FMOC-Glu(biotinyl-PEG)-OH
FMOC-Glu(biotinyl-PEG)-OH

Item number: ABD-5026

This PEG biotin-labeled amino acid has excellent solubility in DMF and other solvents used in SPPS. It is an excellent alternative to FMOC-Lys(biotin)-OH (#5020) due to its improved solubility in both organic solvents and water. In addition, the PEG-spacer reduce the hindrance between the target peptide and avidin,...
