– Liver diseases such as liver cirrhosis, primary and metastatic liver cancers are still a major medical challenge. Syndecan-1 is one of the most important proteoglycans in the liver. Syndecan-1 is normally expressed on the surfaces of hepatocytes and cholangiocytes. Due to liver diseases the amount of syndecan-1 increases in the liver. Syndecan-1 Protein, Human, Recombinant (aa 23-254, His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 25 kDa and the accession number is AAH08765.
