Fig. 1From: Tat-HSP22 inhibits oxidative stress-induced hippocampal neuronal cell death by regulation of the mitochondrial pathwayConstruction and purification of Tat-HSP22 protein. a Diagram of expressed Tat-HSP22 and control HSP22 proteins. Tat-HSP22 expression vector was constructed using pET15b vector. Purification of Tat-HSP22 and control HSP22 protein. After proteins were expressed by IPTG, the proteins were purified using Ni-NTA affinity chromatography. Then, purified proteins were analyzed by b 12% SDS-PAGE and c Western blot analysis with an anti-histidine antibodyBack to article page
