TAMRA is one of the most popular fluorophores used in various bioconjugations. 5-TAMRA is the purified single isomer of 5(6)-TAMRA. It is preferred for some complicated biological applications where reproducibility is more critical than material cost since the minor positional difference between 5-TAMRA and 6-TAMRA might affect some biological properties of the underlying conjugates.

PhosphoBLOCKER™ Blocking Reagent provides superior blocking by maximizing signal-to-noise ratio

Supplier: Invitrogen

Thermo Scientific Pierce Maleimide Activated Horseradish Peroxidase is for preparation of HRP conjugates with proteins, peptides or other ligands that contain sulfhydryl groups, such as reduced cysteines.

Supplier: Invitrogen

Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatized biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4.5 - 5 and requires just minutes to complete.

Thermo Scientific EZ-Link™ Desthiobiotinylation and Pull-down Kit is a complete set of reagents to biotin-label purified proteins and use them to purify interaction complexes using streptavidin agarose resin with mild elution conditions.

Supplier: Invitrogen

Thermo Scientific Pierce EZ-Link Phosphine-PEG3-Biotin is a biotinylation reagent for labeling azide-containing molecules, which enables biotin-based detection and affinity purification of molecules via Staudinger ligation strategies.

Supplier: Invitrogen

Kit has been optimized to incorporate 1-3 biotinylated ribonucleotides (biotin-N4-CTP) onto the 3' end of DNA strands where the label will be less likely to interfere with hybridization or sequence-specific binding of proteins.

Supplier: Invitrogen

Pierce™ NHS-Fluorescein Antibody Labeling Kit is a multi-component kit containing a high-performance derivative of fluorescein dye, activated for easy and reliable labeling of antibodies, proteins and other molecules for use as fluorescent probes.

Supplier: Anaspec

Fluorescein isothiocyanate (FITC) remains one of the most popular fluorescent labeling reagents, probably due to the low cost of the material. 5-FITC and 6-FITC have very similar absorption and fluorescence spectra. However, the isomers may differ in their binding and reactivity to proteins, and the conjugates may elute under different chromatographic conditions or migrate differently in electrophoretic gels.

EasyStain™ is an immunofluorescence reagent designed for use in testing water samples for the presence of Cryptosporidium oocysts and Giardia cysts.

Supplier: Anaspec

AMCA-X, SE is one of the most popular blue fluorescent tagging molecules. It is widely used to label antibodies, proteins and small drug molecules. AMCA-X succinimidyl ester contains a seven-atom aminohexanoyl spacer between the fluorophore and the reactive group.

Supplier: Bulldog Bio
