Abstract
A composition contains an alkaline phosphatase and first to sixth peptide fragments, wherein content ratios of the first to sixth peptide fragments to the alkaline phosphatase satisfy formulas (1) to (6), respectively: (X/Y)×100≤0.6000 (1); (X/Y)×100≤0.1800 (2); (X/Y)×100≤0.2000 (3); (X/Y)×100≤0.8000 (4); (X/Y)×100≤1.6000 (5); and (X/Y)×100≤0.3500 (6), wherein Xto Xrepresent peak area values of the first to sixth peptide fragments calculated by an automatic integration method from an extracted ion chromatogram obtained by an LC-MS/MS analysis of the composition, respectively, and Y represents a peak area value of the alkaline phosphatase calculated by an automatic integration method from a chromatogram obtained by an LC-UV analysis of the composition.
