Antigen Background
The CD44 antigen has been studied under the following names: Pgp-1, Hermes antigen, ECM-III, H-CAM and HUTCH-1. It functions as a homing receptor. CD44 antigen is the cellular receptor for hyaluronic acid. The antibody is also reactive with bone marrow nucleated cells, medullary thymocytes, liver Kupffer cells, fibroblasts, corneal cells, epidermal keratinocytes, synovial cells, a subset of pancreatic acinar cells and brain cells.
Immunogen
circulating malignant human Sezary T cells.
Specificity
Recognizes the CD44 (80-95 kDa) human cell surface glycoprotein on B and T lymphocytes, monocytes, granulocytes and red blood cells. The epitope recognized by this antibody is sensitive to bromelain and other proteolytic enzymes. It is detectable in routine formalin-fixed, paraffin-embedded tissue.
