WebJan 8, 2024 · For the construction of our probes, three different photocrosslinkers were selected: Benzophenone, diazirine and aryl azide, which are the most common classes of reagents for photoaffinity labeling, each with different reactivities and potential background labeling [14,15]. WebNov 9, 2024 · Alkyl diazirines are frequently used in photoaffinity labeling to map small molecule–protein interactions in target identification studies. However, the alkyl diazirines can preferentially label acidic amino acids and acidic protein surfaces in a pH-dependent manner, presumably via a reactive alkyl diazo intermediate. Here, we explore the use of …
WebAug 29, 2013 · Benzophenone-Based Photoaffinity Labeling The synthesis of a benzophenone-based PAP can readily be achieved by linking commercially available functionalized benzophenone derivatives to the probe. Otherwise, the benzophenone motif can be synthesized from a suitable precursor bearing the desired linking unit.
