A monoclonal antibody specific for the internal p19 protein of a type-C retrovirus (HTLV) isolated from human neoplastic T cells has been developed. Its specificity has been shown by radioimmune precipitation and by affinity chromatography of iodinated HTLV proteins. By indirect immune fluorescence this antibody recognizes only HTLV-producing cells. Examination of cells from patients with cutaneous T cell lymphomas and leukemias and with other types of lymphomas and leukemias indicated that HTLV p19 expression is rare. The monoclonal antibody will be useful in determining the natural reservoir of HTLV, possibly in a subset of mature T cell neoplasias.
一种针对从人类肿瘤性T细胞中分离出的C型逆转录病毒(HTLV)内部p19蛋白的单克隆抗体已被研制出来。其特异性已通过放射免疫沉淀法以及碘化HTLV蛋白的亲和层析法得以证明。通过间接免疫荧光法,该抗体仅识别产生HTLV的细胞。对皮肤T细胞淋巴瘤和白血病患者以及其他类型淋巴瘤和白血病患者的细胞进行检测表明,HTLV p19表达罕见。这种单克隆抗体将有助于确定HTLV的天然储存库,可能存在于一部分成熟T细胞肿瘤中。
