Syndecan‑1/CD138 in Human Ileum. Syndecan‑1/CD138 was detected in immersion fixed paraffin-embedded sections of human ileum using Human Syndecan‑1/CD138 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2780) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Syndecan‑1/CD138 in Human Jejunum. Syndecan‑1/CD138 was detected in immersion fixed paraffin-embedded sections of human jejunum using Human Syndecan‑1/CD138 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2780) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Human Syndecan-1 (also known as CD138) is a variably glycosylated, dimeric, type I transmembrane (TM) protein that belongs to the Syndecan family. It is synthesized as a 310 amino acid (aa) precursor that contains a 17 aa signal sequence, a 234 aa extracellular domain (ECD), a 25 aa TM segment, and a 34 aa cytoplasmic region. The ECD shows various degrees of heparan sulfate and chondroitin sulfate modification, leading to native molecular weights for Syndecan-1 of 120 - 200 kDa. Proteolytic cleavage of the membrane-bound ECD yields soluble forms of approximately the same molecular weight. Syndecan-1 is an epithelial cell Syndecan involved in Wnt and chemokine signaling. Human Syndecan-1 ECD shares 71% aa identity with the ECD of both rat and mouse Syndecan-1.
