摘要: 根据GenBank报道的谷氨酸棒杆菌ATCC13032序列,设计并合成一对引物,利用温度梯度PCR仪,获得了argB基因全长。将其克隆到pGEM-T-Easy载体中,经测序鉴定后定向克隆至表达载体pGEX-4T-1中,构建了pGEX-argB表达质粒。

Abstract: The argB sequence was obtained by designing and synthesizing the pair of primer, according to the report of GenBank about the sequence of Corynebacterium glutamicum, assayed by the temperature grads PCR instrument. The argB gene was cloned into plasmid pGEM-T-Easy. The recombinant strain harboring the pGEM-argB plasmid was verified by PCR reaction, plasmid extraction with alkaline method, and digestion with restriction endonuclease BamHI and EcoRI and DNA sequencing. An expressing plasmid pGEX-argB was constructed by the directional cloning of the targeted DNA into the plasmid pGEX-4T-1.
