Using standardized analytical methods amino acids in human serum and plasma were compared. Identical concentrations of the studied amino acids are found in serum and plasma, which are prepared immediately after blood sampling. If protein precipitation is performed after storage of the serum sample at 4 degrees C or 22 degrees C for 10 or 24 hours, concentrations of some amino acids are significantly changed.
使用标准化分析方法对人血清和血浆中的氨基酸进行了比较。在采血后立即制备的血清和血浆中发现所研究氨基酸的浓度相同。如果在4℃或22℃下将血清样本储存10或24小时后进行蛋白质沉淀，则某些氨基酸的浓度会发生显著变化。
