不知道发在这里合适不,实在是求助无门啊!版主手下留情。
在弱碱性(pH 8~9)、暗处、室温或40℃条件下,氨基酸的α-氨基很容易与2,4-二硝基氟苯(缩写为FDNB或DNFB)反应,生成黄色的2,4-二硝基苯氨基酸(dinitrophenyl amino acid,简称DNP-氨基酸)。多肽或蛋白质的N-末端氨基酸的α-氨基也能与FDNB反应,生成一种二硝基苯肽(DNP-肽)。由于硝基苯与氨基结合牢固,不易被水解,因此当DNP-多肽被酸水解时,所有肽键均被水解,只有N-末端氨基酸仍连在DNP上,所以产物为黄色的DNP-氨基酸和其它氨基酸的混合液。混合液中只有DNP-氨基酸溶于乙酸乙酯,所以可以用乙酸乙酯抽提并将抽提液进行色谱分析,再以标准的DNP-氨基酸作为对照鉴定出此氨基酸的种类。因此2,4-二硝基氟苯法可用于鉴定多肽或蛋白质的N-末端氨基酸。
那为什么SFDA不批准CA199CEAAFP等检测试剂盒作为癌症检测的手段呢?
荧光标记物常用的有几十种,比如FITC, PE等等,各个生产厂家还有自己的专利产品
