photoaffinity labelling (medicine)


photoaffinity labelling
<technique> A technique for covalently attaching a label or marker molecule onto another molecule such as a protein.

The label, which is often fluorescent or radioactive, contains a group that becomes chemically reactive when illuminated usually with ultraviolet light) and will form a covalent linkage with an appropriate group on the molecule to be labelled: proximity is essential. The most important class of photoreactive groups used are the aryl azides, which form short lived but highly reactive nitrenes when illuminated.
