Syndecan-1
  
  • All IHC stains will include a positive control tissue
  
  • CD138 is a very useful marker in identifying plasma cells
  • This antibody will identify plasmacytomas/multiple myeloma, plasmocytic lymphomas, and some cases of immunoblastic lymphoma with plasmacytoid differentiation
  • CD138 can be used in a panel with bcl-6, to help divide the HIV associated lymphomas into those of follicular origin (bcl-6 + / CD138 -) and those of post-follicular origin (bcl-6 - / CD138 +)
  • CD138 staining has been shown to be present in normal epidermis, squamous cell carcinoma in situ, and keratoacanthomas; in contrast, invasive squamous cell carcinomas show markedly reduced staining

Specifications

  • CD138 is a plasma cell-associated transmembrane heparan sulfate proteoglycan, that mediates cell to matrix adhesion; its expression is inversely correlated with tumor aggressiveness and invasiveness
  • CD138 is expressed in plasma cells, as well as pre-B cells, post-follicular immunoblasts
  • CD138 can react with Reed-Sternberg cells (classical Hodgkin's disease, results vary from high degree of staining in some studies, to only stromal staining in other studies)
  • This antibody is not specific for plasmacytic derivation, since it will also stain epithelial cells (keratinocytes, and simple and stratified epithelial cells), as well as stromal cells and melanocytic cells (see below)
  • CD138 expression is not definitive for plasmacytic derivation, unless a hematolymphoid phenotype has been established, and a possible epithelial or stromal (including melanocytic) process has been excluded

Staining pattern

  • Cell surface membrane staining
