鉴于基因工程抗体具有分子小、免疫原性低，不被细胞受体结合，在体内成象定位检查时本底低，图像清晰，能进入实体瘤周围微循环，在治疗实体瘤时较完整抗体分子的效能高等优点。我们从肝癌特异性ｍＡｂＨＡｂ１８中克隆了其轻、重链可变区基因，并测定了其核苷酸序列，为... In view of genetically engineered antibodies with small molecules, low immunogenicity, not by cell receptor binding, imaging in situ imaging low background check, clear images, can enter the solid tumor around the microcirculation in the treatment of solid tumors more complete antibodies The advantages of higher molecular efficiency. We cloned the light and heavy chain variable region genes from hepatoma-specific mAb HAb18 and determined their nucleotide sequence as ...
