METHODS: The HAb18GEF gene fragment was amplified by PCR and digested with Sac I/Not I,and then cloned into the multiple clone site downstream of EpoR/LR-F3 gene of eukaryotic expression vector pCEL2f.

• 方法:用PCR法扩增肝癌相关抗原HAb18G胞外段基因,SacI/NotI双酶切后插入真核表达载体pCEL2f中,构建EpoR/LR-F3/HAb18GEF嵌合受体基因的重组表达载体pCEL2f/HAb18GEF,并经酶切和测序验证。
