Peptides immunoreactive with antibodies to native proteins, and which have at least two cysteine residues that contribute to mimicking an epitope of the protein, are prepared with the cysteine thiol groups protected. When deprotected, the peptides have enhanced immunoreactivity. The peptides are particularly useful for detecting antibodies or antigens associated with retroviruses, including the clinically important lymphotropic retroviruses HIV-1, HIV-2, HTLV-I, and HTLV-II
具有至少两个半胱
氨酸残基,与天然蛋白质
抗体免疫反应,且有助于模拟蛋白质表位的肽,使用半胱
氨酸巯基保护,制备出来的肽具有增强的免疫反应性。这些肽特别适用于检测与逆转录病毒相关的
抗体或抗原,包括临床重要的淋巴病毒HIV-1、HIV-2、HTLV-I和HTLV-II。
