Recombinant CCN2 protein (rCCN2) is available from many companies; however, most of them are produced in E. coli. To investigate true functions of rCCN2, glycosylated protein with proper folding needs to be used. Therefore, we use rCCN2 produced by mammalian cells. Conditioned medium (CM) of HeLa cells stably transfected with a CCN2 expression vector are collected, and the recombinant CCN2 protein produced and secreted into the CM is purified by two-step chromatography, first with a heparin affinity column and then with an anti-CCN2 affinity column prepared with a monoclonal antibody against CCN2. The purified rCCN2 shows the bands of 36–38 kDa with sliver staining after gel electrophoresis, which can be confirmed by Western blotting. This chapter describes these methods in detail.
