XM_003472337） published in Gen Bank, a pair of primers was designed to amplify ESR2 gene coding sequence（CDS） of C. porcellus using RT-PCR. Then the obtained fragments were sequenced and indentified. The physicochemical properties and protein secondary structure of ESR2 was predicted and analyzed using bioinformatics software. 【Result】The CDS of cloned ESR2 gene in C. porcellus was 1650 bp in length, encoding 549 amino acids, and which differed with reference |
