λ light chain gene encoding the expression protein was amplified by polymerase chain reaction(PCR) from infectious bursal B lymphocyte cDNA library, and inserted into the corresponding sites of vector pUC19 after digested by restriction endonuclease to construct protocaryon expression vector PET43a.Both nucleotide sequencing and BamHⅠ and HindⅢ digestion confirmed that λ light chain gene fragment encoding the target protein was correctly inserted into the vector.The recombinant plasmid was transformed into E.coli BL21(DE3) and induction by IPTG and SDS-PAGE indicated that the target protein was expressed.
