生物样品(蛋白质水解液、血浆中色素)及微量元素锌(zn)对氨基酸分析均有不同程度的影响。Ito和wunderly等人先后的研究结果证实了活性炭对氨基酸具有吸附性,故不能用于氨基酸样品的预处理。为了适应蛋白质氨基酸研究的需要,本文用
Biological samples (protein hydrolyzate, plasma pigment) and trace element zinc (zn) have varying degrees of impact on amino acid analysis. Previous studies by Ito and Wunderly et al. Have confirmed that activated carbon is adsorptive to amino acids and therefore can not be used for the pretreatment of amino acid samples. In order to meet the needs of protein amino acid research, this article used
