VS38

Immunohistochemical expression

This commercially available antibody is directed against a protein of the endoplasmic reticulum.  It is a sensitive marker for plasma cells.  Positive staining is seen in plasma cell, plasmablasts, lymphoplasmacytoid cells, and B-immunoblasts.  However, positivity has been reported in other tumours, including melanocytic lesions, neuroendocrine tumours and many epithelial tumours.
