采用氯胺－Ｔ法标记了３种不同来源的人血白蛋白。用预饱和的Ｓｅｐｈａｄｅｘ Ｇ５０柱分离纯化１２５Ｉ标记人血白蛋白，并用ＨＰＬＣ法对标记物进行分析鉴定。取分离后的１２５Ｉ标记白蛋白配制示踪液，进行家兔体内代谢试验。用氯胺－Ｔ方法，１２５Ｉ标记人血白蛋白的标记率＞８０％。代谢研究表明，成都生物制品研究所柱层析、低温乙醇工艺和加拿大技层析工艺生产的人血白蛋白，其生物半减期分别为９６．１１±０．０１、８５．７５±２．６２和９０．００±１．６９，三者之间无显著性差异（＞０．０５）。
Three different sources of human albumin were labeled with chloramine-T method. 125I-labeled human albumin was separated and purified from pre-saturated Sephadex G50 column, and the marker was identified by HPLC. Take isolated 125I labeled albumin preparation tracer, the rabbit in vivo metabolic tests. With chloramine-T method, 125I labeled human serum albumin labeling rate> 80%. Metabolic studies have shown that the biological half-life reduction of the human serum albumin produced by the Chengdu Institute of Biological Products column chromatography, low temperature ethanol technology and Canadian technology chromatography process were 96.11 ± 0.01, 85.75 ± 2. 62 and 90.00 ± 1.69, no significant difference between the three (> 0.05).
