作者报道利用噬菌体系统可生产一种针对性较强的抗癌胚抗原(CEA)抗体.用CEA免疫小鼠,提取脾细胞中的mRNA,并反转录成cDNA.用特异性引物并以cDNA为模板,经聚合酶链反应(PCR)扩
The authors report that a phage-based system can produce a more specific anti-carcinoembryonic antigen (CEA) antibody.The mice were immunized with CEA, mRNA in spleen cells was extracted and reverse transcribed into cDNA.Using specific primers and cDNA As a template, amplified by polymerase chain reaction (PCR)
