Syndecan-1, encoded by SDC1, is involved in myoblast development and engages in protein-protein interactions critical for cellular functions. Its location on the cell surface suggests a role in cell communication and signaling. Syndecan-1s broad expression profile across various tissues underscores its significance in different physiological contexts. Its evolutionary conservation with human SDC1 highlights its fundamental role across species. Syndecan-1/CD138 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Syndecan-1/CD138 protein, expressed by HEK293 , with C-His labeled tag.
