蛋白质的定量分析是生化研究、临床化验和食品检验等领域经常涉及的内容．以有机小分子作光谱探针测定蛋白质，如甲基橙［１，２］、考马斯亮蓝Ｇ－２５０［３］、溴酚蓝［４］、溴甲酚绿［５］和偶氮胂Ⅲ［６］等已得到研究．本文研究表明，在室温条件下，硝基磺酚Ｃ能与... Quantitative protein analysis is often involved in biochemical research, clinical laboratory tests and food testing. Small organic molecules as spectroscopic probes for the determination of proteins such as methyl orange [1,2], Coomassie brilliant blue G-250 [3], bromophenol blue [4], bromocresol green [5] and arsenazo III [6] etc. have been studied. This study shows that at room temperature, nitrosulphol C with ...
