| 摘 要： | 采用基体辅助激光脱附和电离法，分别以肉桂酸和２；５－二羟基苯甲酸作为基体，在飞行时间质谱中测得细胞色素Ｃ的相对分子质量为１２７８０ｕ；并观察到它的多聚体离子。实验结果表明，肉桂酸是比较理想的基体，同时还考察了Ｎａ＋离子存在对测定结果的影响。

| Abstract: | Two matrices, cinnarnic acid and 2,5-dihydrobenzic acid, are used for the study ofmatrix-assisted laser desorption/ionization time-of-flight mass spectrometry of cytochromeC. The results show that the molecular weight of cytochrome C is determined to be 12780u and the cinnamic acid is more sllitable as a matrix material. In addition, the presenceof Na+ in the sample solution could strongly affect the results. |
