摘要
Abstract
The total RNA was abstracted from the concanavalin A(Con A) -activated spleen lymphocytes, a pair of specific primers was designed by Oligo software based on the sequence of chicken interferon-gamma submitted by digby in GenBank (accession No. U27465). A 500 bp DNA fragment was amplified by reverse transcription-polymerase chain reaction (RT-PCR) and then ligated into T-easy vector for sequencing. The results showed that the fragment contained the complete open reading frame (ORF) of CHIFN-r gene. In comparison with GenBank data, the homology of the nucleotide sequence was 100%. The sequence was inserted into pGEX-4T-1 and the recombined expressing vector was constructed, then transformed into Escherichia coli BL21, which were further induced by IPTG and cultured,and a fusion protein was obtained with about 43 ku of molecular weight in SDS-PAGE. This results showed that the cloned CHIFN-y gene was expressed in prokaryotic cells.关键词
