Dnph assay
WebAn assay method for detection of enantiospecific chiral alcohol was developed based on ketoreductase, enantio-selective alcohol oxidase and 2,4-dinitrophenyl hydrazine (DNPH) reagent. The assay method was developed to check the conversion of 1-Acetonapthone to either (S) or (R) specific 1-(1-napthyl … WebGiven the efficiency of this assay coupled with its multiwell format, the 2,4-DNPH α-KG assay may be adaptable to explore non-HIF substrates of PHDs and potentially to high-throughput assays. Keywords: 2,4-dinitrophenylhydrazine; enzyme kinetics; high-throughput assay; in vitro hydroxylation; prolyl hydroxylase; α-ketoglutarate-dependent ...
