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.

Supplier: Thermo Scientific

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.

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.
