Recombinant Human CST7 protein (NP_003641.3) is produced in Sia-Increased Human Cell Lines. This expression system is used for the production of glycoproteins with high sialylation and core fucosylation.
The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens.
