p-Nitrobenzyl mesylate (PNBM) is a reagent that is used to alkylate thiophosphates, forming thiophosphate ester epitopes that can be recognized by specific antibodies.[1] Substrates phosphorylated with adenosine 5'-(γ-thio)-triphosphate or N6-benzyl-ATPγS can be alkylated by PNBM.[2],[3] The tagged substrates can be isolated by immunoprecipitation or immunoaffinity purification, or they can be detected by immunoblotting.
