cDNA cloning and prokaryotic expression of human neural RNA binding protein HuC / 基础医学与临床

ABSTRACT

Objective To clone human neural RNA binding protein HuC cDNA,express and purify the recombinant human HuC(Hu antigen C)protein in E.coli.Method Human HuC cDNA was cloned by RT-PCR.HuC cDNA was inserted into the prokaryotic expression vector pGEX-4T-3.The recombinant protein HuC was expressed in E.coli BL-21,and purified by the GST Sepharose 4B affinity column.Results The(62 ku) recombinant GST-HuC fusion protein was obtained.Conclusion The recombinant human HuC protein was successfully prokaryotic expressed and purified.
