| Abstract: | With the purified mRNA from hybridoma which secrete monoclonal antibodies against a 40 ku adipocyte plasma membrane protein, the V_(H) (heavy-chain variable region) and V_(L) (light-chain variable region) genes encoding the monoclonal antibody were amplified by RT-PCR, then they were joined with Linker for construction of scFv gene. The results showed that the scFv gene had been constructed in the way of V_(H)-linker-V_(L). Sequence analysis demonstrated that length of the scFv gene was 741 bp and length of V_(H) and V_(L) genes was 369 bp and 327 bp respectively. The constructed scFv gene can be used to express the antibody. |
