Cross linkers are used for the identification of near-neighbour protein relationships and ligand-receptor interactions. Homobifunctional, amine-reactive NHS esters or imidates, and heterobifunctional, amine-reactive, photoactivatable phenyl azides are the most commonly used crosslinkers for these applications.

Photoactivatable Biotin, Biotin-LC-ASA , Psoralen-PEG3-Biotin and TFPA-PEG3-Biotin each contain a photoactivatable group. When exposed to UV light, they become activated and insert non specifically into nearby molecules. These reagents may be used to label proteins and peptides, but they are also useful in labeling DNA, RNA and other molecules that do not contain any readily reactive functional groups. Psoralen-PEG3-Biotin contains a reactive psoralen group and is
designed to efficiently label nucleic acids. The psoralen group intercalates into the helix of DNA, allowing it to label efficiently and selectively. The psoralen can also stack along with the bases of single-stranded DNA or RNA increasing labeling efficiency and selectivity.

The NHS-Azide and NHS-Phosphine Reagents are amine-reactive compounds for derivatising primary amines of proteins or amine-coated polymer surfaces. Once a protein or surface is azide- or phosphine-labelled, the two components are mixed for effective and stable conjugation. Phosphine groups react with azides via a Staudinger reaction to produce an aza-ylide intermediate that is trapped to form a stable, covalent amide bond. Because phosphines and azides are absent from biological systems, there is minimal background labelling of macromolecules found in cells or lysates.

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

The DyLight™ Long Stokes Shift Dyes are amine-reactive fluorescent dyes that produce long Stokes (LS) shifts of 80 to 145 nm in excitation/emission wavelengths. The DyLight™ LS dyes provide multicolour detection using a single excitation source in applications including flow cytometry, conjugation, DNA-sequencing, microscopy and fluorescence in situ hybridization (FISH). These dyes contain N-hydroxysuccinimide (NHS) esters, the most commonly used reactive group for labeling proteins. NHS esters react with primary amines on proteins and other molecules, forming a stable, covalent amide bond and releasing the NHS group.

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.

HOOK™ Biotin-Hydrazide and its long spacer arm equivalent, HOOK™ Biotin-LC-Hydrazide, are carbohydrate reactive reagents. HOOK™ carbohydrate reactive biotin reagents react with oxidised carbohydrate side chains. Some biotin reagents do not bind directly to the protein itself, but instead, conjugate to the carbohydrate residues of glycoproteins. The carbohydrate reactive biotin reagents contain hydrazides (-NH-NH₂) as a reactive group. The hydrazide reactions require carbonyl groups, such as aldehydes and ketones, which are formed by oxidative treatment of the carbohydrates. Hydrazides react spontaneously with carbonyl groups, forming a stable hydrazone bond. These reagents are particularly suitable for labelling and studying glycosylated proteins, such as antibodies and receptors.

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.
