Protein Carbonyl Content Assay Kit (ab126287) Abcam

Webb3 sep. 2014 · Most carbonyl assays rely on the reaction of 2,4-dinitrophenylhydrazine (DNPH) with the carbonyl moiety of amino acid side chains, resulting in a stable covalent bond between DNP (dinitrophenylhydrazone) and the protein (26,27,30,31). The Protein Carbonyl Content Assay Kit provides a simple and direct procedure for measuring carbonyl content in a variety of biological samples. Carbonyl content is determined by the derivatization of protein carbonyl groups with 2,4-dinitrophenylhydrazine (DNPH) leading to the formation of stable dinitrophenyl (DNP) hydrazone adducts, which ... brews ab https://officejox.com
