Abstract

一种HIV阳性血清的替代物,是将非人的抗HIV抗体或其处理液与正常人免疫球蛋白或其处理液通过交联反应得到的交联物。本发明的实质是把非人的抗HIV的抗体活性(即与HIV抗原的反应活性)和正常人免疫球蛋白的抗原活性(即与抗人免疫球蛋白抗体酶结合物的反应活性)相结合,从而达到消除人抗致病因子抗体阳性血清(或血浆)中可能带有致病因子的危险性又具备抗致病因子抗体阳性血清的反应性的目的,本发明的替代物来源于非人的抗HIV抗体和正常人免疫球蛋白,因此从根本上避免了阳性血清潜在感染的危险性。

Description

一种HIV阳性血清的替代物
技术领域
本发明涉及免疫生化领域,特别涉及一种HIV阳性血清的替代物。
背景技术
现有技术中,对于检测人类兔疫缺陷病毒抗体,通常采用酶联免疫试剂盒,此种试剂盒的阳性对照血清经过灭活处理,但是目前对于试剂盒中HIV抗体的能保持活性,同时试剂盒中HIV病毒彻底灭活的方法并没有定论。
发明内容
本发明所要解决的技术问题是:由于现有技术中检测人类兔疫缺陷病毒抗体试剂盒中阳性对照血清可能存在潜在的感染,这样对于需要检测的人来说有一种潜在的危险,本发明为解决已有技术中的上述技术问题,所采用的技术方案是提供一种HIV阳性血清的替代物,所述的替代物是将非人的抗HIV抗体或其处理液与正常人免疫球蛋白或其处理液通过交联反应得到的交联物。本发明的实质是把非人的抗HIV的抗体活性(即与HIV抗原的反应活性)和正常人免疫球蛋白的抗原活性(即与抗人免疫球蛋白抗体酶结合物的反应活性)相结合,从而达到消除人抗致病因子抗体阳性血清(或血浆)中可能带有致病因子的危险性又具备抗致病因子抗体阳性血清的反应性的目的,其中非人的抗HIV抗体可以是单克隆抗体。基因工程抗体或HIV抗原(病毒裂解物或合成肽或基因工程肽)免疫动物得到的抗体。可以是完整的抗体或具抗体活性的片段。正常人免疫球蛋白是指无抗HIV抗体活性的人免疫球蛋白,即经酶免疫测定法(EIA)检测HIV为阴性的人免疫球蛋白,可以是完整的人免疫球蛋白或其片段。交联的方法有多种,如常用的有戊二醛法、苯酮法等。
本发明和已有技术相对照,本发明的替代物来源于非人的抗HIV抗体和正常人免疫球蛋白,因此从根本上避免了阳性血清潜在感染的危险性。
具体实施方式:
实施例1:
①将8mg抗HIV单克隆抗体溶解于2ml 0.1M PH7.5 PBS,于23℃下,搅拌加入0.2umol SPDP,反应30分钟后,装透析袋,对0.1M PH7.5PBS透析,换液四次。
②将16mg人两种球蛋白(抗HIV抗体活性经EIA检测为阴性)溶解于2ml 0.1M PH7.5 PBS,于23℃下,搅拌加入0.4umol SPDP,反应30分钟后,装透析袋,对0.1M PH4.5醋酸盐缓冲液透析,换液四次。加入终浓度为25mM的DTT于23℃下,反应30分钟,装透析袋,对0.1M PH7.5PBS透析,换液四次。
③将①、②中的处理物混合,于23℃反应1小时,于4℃下反应24小时,即得交联物,离心会沉淀,上清用正常人血清或血浆稀释备用,并加入万分之一疏柳汞防腐,特性不变。
