Dnph assay for mammalian cells

WebApr 15, 2016 · Many biochemical and analytical methods have been developed during the last thirty years to assay protein carbonylation. The most successful method consists on protein carbonyl (PCO) derivatization with 2,4-dinitrophenylhydrazine (DNPH) and consequent spectrophotometric assay. WebThe assay detects mutations in the thymidine kinase ( Tk) gene. The Tk mutants recovered in the MLA can be classified as large and small colonies, indicating the potential for the test chemical to induce gene mutations and/or chromosomal mutations, respectively, and thus revealing the mutagenic mode of action of test agents.
