Abstract:
To investigate the function of CTCF and understand the pathogenesis of tumors better, we produced rabbit polyclonal antibody of human transcription factor CTCF protein and detected its expression in several kinds of human cancer cells and tissues. GST fusion protein of human CTCF-N domain was purified by GSTrap-FF affinity chromatography and was successfully expressed under induction of IPTG in E. coli BL21. Western blotting analysis demonstrated that the polyclonal antibody can recognize the endogenous CTCF from HepG2, MCF-7 and HeLa cells specifically. The produced antibodies can be used for gene expression regulation and tissue distribution study at protein level.
