After enzyme digestion and sequencing verification, it was confirmed that the expression vector was successfully constructed.Then, the pLVX-JNK3-IRES-ZsGreen1 expression vector was transfected into SHSY5Y cells using Lipofectamine 3000 reagent. The transfected cells were screened, and the cells expressing green fluorescent protein were selected by fluorescence microscopy. After PCR confirmation, a stable JNK3 expression cell line was screened.Finally, Western blot was used to confirm the presence of JNK3 protein in stable JNK3 expression cell line, and an appropriate stable expression cell line was identified.The results of this study indicate that the human JNK3 eukaryotic expression vector was successfully constructed, and a stable JNK3 expression cell line was established, laying the foundation for the study of the regulatory mechanism of JNK3 and its relationship with related diseases.精品文档---下载后可任意编辑【Keywords】JNK3; eukaryotic expression vector; stable transfection; JNK3 expression cell line
