Description
In the general process of expressing the recombinant Escherichia coli sta2 protein, a plasmid encoding the Escherichia coli sta2 protein (54-72aa) is constructed first. The plasmid is transferred into e.coli cells, from which cells containing the plasmid are selected and cultured to express the protein. A N-terminal 10xHis-SUMO tag and C-terminal Myc tag is fused to the protein. The recombinant Escherichia coli sta2 protein undergoes affinity purification purification and SDS-PAGE analysis. This protein surpasses a purity level of 85%.
