【摘要】 Neuritin是一种新发现能促进神经突起和轴突分支的蛋白,为了更清楚的研究它的生物学功能,在已克隆Neuritin cDNA的基础上,PCR扩增出Neuritin ORF,与原核表达载体pET32a重组后,成功的构建了Neuritin原核表达质粒pET32a-Neuritin。重组质粒转化B121大肠杆菌,IPTG 诱导后,表达产物用SDS-PAGE和Western blot证实系Neuritin,用镍离子亲和层析的方法获得了纯化的Neuritin蛋白。更多还原

【Abstract】 Neuritin is a new neurotrophic factor found recently. In order to identify the function of Neuritin clearly, the coding sequence of human neuritin was amplified by PCR from neuritin cDNA , this fragment digested by NocI and NotI was inserted into pET32a by T4 ligase and transformed into E. coli BL21 then the recombinant plasmid named pET32a-neuritin was constructed successfully . Neuritin was expressed distinctly after inducing by EPTG. The product was identified as neuritin by SDS-PAGE and Western blot analysis . The expression production was purified on Ni2+-NTA column.更多还原
