FITC (fluorescein isothiocyanate) is a commonly used fluorescent label for proteins, as it contains the groups required for conjugating to amino, sulfhydryl, imidazoyl, tyrosyl or carbonyl groups of proteins. FITC has a molecular weight of 389, and excitation and emission wavelengths of 494 nm and 520 nm, respectively, therefore emitting green visible light.

Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatised 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 to 5 and requires just minutes to complete.

Microscale optimised for labelling 50 µg antibody per reaction. Many biological compounds present in cells, serum or other biological fluids are naturally fluorescent, and thus the use of conventional, prompt fluorophores leads to serious limitations in assay sensitivity due to the high background caused by the autofluorescence of the biological molecules to be assayed.

Photoreactive agents, on exposure to ultraviolet light, become active and bind non specifically with neighbouring molecules. These reagents are suitable for labelling molecules that do not contain easily reactable functional groups. Photoreactive reagent HOOK™ Psoralen-PEO-Biotin reacts with and labels nucleic acids and protein molecules. When reacted with nucleic acids, it crosslinks with pyrimidine bases. Crosslinking does not interfere with hybridisation applications.

The DyLight™ Specialty Dyes are fluorescent dyes with varying spectral characteristics, degrees of sulfonation, charges and hydrophobicities. These dyes are offered in their amine-reactive forms and are mainly derivatized with N-hydroxysuccinimide (NHS) esters, the simplest and most commonly used reactive group for labeling proteins. The large selection of near infrared (NIR) and infrared (IR) dyes may be used for in vivo and near-IR fluorescence (NIRF) applications.
