BACKGROUND Previous methods to measure glycohemoglobin (GHb) have been time-consuming or imprecise; we therefore developed a new enzymatic assay for GHb. METHODS Blood cells were first hemolyzed, and hemoglobin was digested with protease to yield fructosyl amino acid. Fructosyl amino acid oxidase acts on the fructosyl amino acid and generates hydrogen peroxide, which reacts with chromogens in...
We partly purified R-factor-encoded chloramphenicol acetyltransferase (EC 2.3.1.28) from a highly choloramphenicol-resistant mutant derived from Escherichia coli W677/R5. The preparation permitted rapid quanitation of chloramphenicol by use of [14C]acetylcoenzyme A, removing the diacetylated product by selective adsorption onto micropore filters. Succinyl and glucuronyl 3-hydroxyl esters of chl...
