    • This invention relates to compositions and methods for the detection of HIV-1 antibodies employing polypeptides obtained from the Gag-p6 protein, the method comprising the steps of: (a) contacting a biological sample with a peptide having an epitope that is recognized by the anti-HIV-1 antibody where the contacting is under conditions sufficient to permit anti-HIV-1 present in the sample to bind to the epitope and form a peptide-anti-HIV-1 antibody complex; (b) contacting the formed peptide-anti-HIV-1 antibody complex with an anti-HIV-1 antibody binding molecule under conditions sufficient to permit the anti-HIV-1 antibody binding molecule to bind to anti-HIV-1 antibody of the formed peptide-anti-HIV-1 antibody complex and form an extended complex; said extended complex being immobilized on a solid support; and (c) removing unbound antibody from said extended complex; and (d) determining the presence or concentration of the anti-HIV-1 antibody in the biological sample by determining the presence or concentration of the formed extended complex.
    • 本发明涉及使用从Gag-p6蛋白获得的多肽检测HIV-1抗体的组合物和方法,所述方法包括以下步骤:(a)使生物样品与具有由所述 抗HIV-1抗体,其中接触条件足以使样品中存在的抗HIV-1与表位结合并形成肽 - 抗HIV-1抗体复合物; (b)在足以允许抗HIV-1抗体结合分子结合抗HIV-1抗体结合分子的抗HIV-1抗体的条件下,使所形成的肽 - 抗HIV-1抗体复合物与抗HIV-1抗体结合分子接触 形成肽 - 抗HIV-1抗体复合物并形成扩展复合物; 所述扩展的复合物被固定在固体支持物上; 和(c)从所述扩展复合物中除去未结合的抗体; 和(d)通过确定所形成的扩展复合物的存在或浓度来确定生物样品中抗HIV-1抗体的存在或浓度。
