Abstract: 【OBJECTIVE】To clone and analysis the FcRn gene of pig.【METHOD】Total RNA was extracted from mucosal tissue of duodenum and mRNA sequence of gene were amplified by RT-PCR using two designed primers. The PCR products were ligated into the pMD-19T vector, and then transformed into competent cells of JM109. The sequence was analyzed to identify the recombinant plasmid.【RESULTS】Identity analysis showed that the two FcRn nucleotide sequence shared 99 % 【CONCLUSION】The porcine alternatively spliced variant of FcRn gene was successfully cloned in the present study and the sequence of spliced variant has been submitted to GenBank(Accession. EU852582)
