Product Specifications

Background

Cystatin-5 (CST5) is also known as Cystatin-D, is a secreted thermostable protein, which belongs to the cystatin family. CST5 is a cysteine proteinase inhibitor that possibly plays a protective role against proteinases present in the oral cavity. The order of preference for inhibition is cathepsin S > cathepsin H > cathepsin L > cathepsin B. CST5 / cystatin-D may play a protective role against proteinases present in the oral cavity.

Specifications
