Abstract:
OBJECTIVE: To clone the transmembrane (TM) domain sequence of EGFR gene and lay a good foundation for constructing the transmembrane expression vector of recombinant superantigens and cytokines. METHODS: A pair of primers special to the sequence encoding TM domain of EGFR gene were synthesized, TM domain fragment was cloned by RT-PCR, and the PCR product of TM domain sequence was ligated with the pGEM-T vector and confirmed by DNA sequencing. RESULTS: TM domain sequence was successfully cloned and verified by DNA sequencing. CONCLUSION: The successful cloning of TM domain sequence provides a basis for the construction of transmembrane fusion protein of Superantigen-TM or Cytokines-TM in cancer biotherapy.
