利用凝胶切割纯化法得到免疫纯人血清白蛋白（ＡＬＢ），经聚丙烯酰胺凝胶（ＰＡＣ）电泳确认为单一带，经ＳＤＳ－ＰＡＣＥ确定其相对分子质量为６７４６２．８０Ｕ，与Ｓｉｇｍａ纯品ＡＬＢ及日本产羊抗人ＡＬＢ抗血清免疫双扩散融合试验验证其为纯品ＡＬＢ。利用得到的ＡＬＢ免疫绵羊制备羊抗人白蛋白抗血清，与日本产品比较，为单价特异性抗血清。
Immuno-pure human serum albumin (ALB) was obtained by gel-cutting and purification method. The polyacrylamide gel (PAC) electrophoresis was used as a single band. The relative molecular mass was 67462.80U by SDS-PACE, ALB and Japanese goat anti-human ALB antiserum double immunodiffusion fusion test proved to be pure ALB. The obtained sheep immunized with ALB were used to prepare goat anti-human albumin antiserum, which was monovalent specific antiserum compared with Japanese products.
