PDGF-BB/PDGFB Antibody Staining Protocol for Immunohistochemistry


Description: PDGF-B is the major polypeptide mitogen in serum for cells of mesenchymal origin; it promotes cellular proliferation and inhibits apoptosis. Immunohistochemistry: LS-B4182 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval.
