【Objective】In order to establish the foundation for transgenic mouse model,the human thalassemic gene(β654) was cloned and sequenced.【Methods】The human β654 gene was amplified by PCR,and cloned into the plasmid BGT51 in which the human β gene was cut out aforehand.The recombinant plasmid was certified by enzyme-digestion,reverse dot hybridization and sequencing.【Results】A recombinant plasmid was obtained,which contained the human β654 gene in the correct recombinant direction.Sequencing showed that the cloned insert was correct.【Conclusions】The recombinant plasmid constructed is useful for establishing a transgenic mouse.
