To construct and screen the human phage antibody library from a patient with melanoma.
Total RNA was extracted from the peripheral blood mononuclear cells (PBMCs) of a patient with melanoma who has survived for twenty years. The heavy chain Fd fragments and kappa light chains were amplified by RT-PCR. The amplified products were cloned into phagemid vector to construct Fab antibody library. The library was panned with two kinds of melanoma cells for 4 rounds.
Antibody library contained 1.2 x 10(8) different clones. Specific phage antibodies against one of the two melanoma cells were obtained after 4 rounds of panning.
Specific human phage antibodies against melanoma cells were obtained.
构建并筛选来自一名黑色素瘤患者的人噬菌体抗体库。
从一名存活20年的黑色素瘤患者的外周血单个核细胞（PBMCs）中提取总RNA。通过逆转录聚合酶链反应（RT-PCR）扩增重链Fd片段和κ轻链。将扩增产物克隆到噬菌粒载体中构建Fab抗体库。该库用两种黑色素瘤细胞进行4轮淘选。
抗体库包含1.2×10⁸个不同的克隆。经过4轮淘选后获得了针对两种黑色素瘤细胞之一的特异性噬菌体抗体。
获得了针对黑色素瘤细胞的特异性人噬菌体抗体。
