This method obtains peptide fragments having ends of specific amino acids from a protein, which does not use an enzyme and thus is associated with minimum contamination. An organic acid represented by a general formula; CF3-(CF2) n-COOH, wherein n is an integer of 0 or larger, is allowed to act on a protein or peptide.
这种方法可以从蛋白质中获得具有特定
氨基酸末端的肽片段,无需使用酶,因此污染最小。通式为
CF3-(
CF2) n-COOH(其中 n 为 0 或更大的整数)的有机酸可作用于蛋白质或肽。
