电泳(SDS-PAGE)

Human Cystatin D, His Tag (Cat. No. CS5-H5220) SDS-PAGE gel

Human Cystatin D, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

背景(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.
