Such as when the substrates was benzidine and a - naphthol , the absortion peak was 450nm after catalyticed by dna , and 501nm after catalyticed by pod , if changing substrate to benzidine and pyrocatechol , the absortion peak was 503nm after catalyticed by dna and 603nm after catalyticed by pod . the second difference was the different result after hplc : the result of hplc ( substrates : benzidine and a - naphthol ) showed that the products under the affect of dna and pod had different value on the peak and the area 然后對以聯(lián)苯胺與-萘酚為底物,以h _ 2o _ 2為氧化劑,進行高效液相色譜分析,分析結(jié)果表明dna與過氧化物酶作用后的產(chǎn)物在峰面積和峰高上有不同數(shù)值;同時,不同形式的dna對該反應(yīng)都有催化活性,表明只要是生物來源的dna (非特異性dna )都具有一定程度的催化活性。
