新疆细毛羊eIF3l基因的克隆、原核表达及蛋白检测
Cloning, prokaryoctic expression and protein measurement of the gene eIF3l in Xinjiang Fine-wool sheep
摘要
Abstract
In order to study the sequence characteristics,expression in E.coli BL21 (DE3) and identification of protein in vitro of eukaryotic translation initiation factor 3 L gene (eIF3l) in Xinjiang Fine-wool sheep,we cloned the CDS encoding sequence of eIF3l gene from the Xinjiang Fine-wool sheep fibroblasts by RT-PCR,and constructed the prokaryotic expression vector,induced the expression.The results showed that eIF3l gene sequences of CDS was got successfully,and the length of the CDS was 1 695 bp and coded 564 amino acids.The E.coli containing recombinant vector expressed inclusion body proteins of 69 ku after induction by 1 mmol/L IPTG.Western blotting revealed that the expressed protein was the target protein,which indicated that the recombinant prokaryotic expression vector expressed successfully.Together,our works made a foundation for the study of function and application of the eIF3l gene.关键词
