Background
CD87 is a glycoprotein encoded by the PLAUR gene and anchored to the cell membrane surface via glycosylphosphatidylinositol (GPI), playing a critical role in cell migration, tissue remodeling, and signal transduction. As a high-affinity receptor for urokinase-type plasminogen activator (uPA), CD87 confines uPA-mediated plasminogen activation to the cell surface, thereby promoting localized degradation of the extracellular matrix—a function that is essential in both physiological processes such as wound healing, embryo implantation, and angiogenesis, as well as pathological processes including tumor invasion, metastasis, and inflammation. In addition, beyond serving as a platform for proteolysis, CD87 participates in the regulation of intracellular signaling pathways through interactions with integrins, urokinase-type plasminogen activator, and vitronectin, thereby influencing cell adhesion, proliferation, and survival. This protein also exists in a soluble form (suPAR), released into the blood upon proteolytic cleavage of cell-surface CD87 or disruption of its GPI anchor, and its circulating levels correlate with the severity and prognosis of various diseases. Clinically, CD87 is highly expressed in multiple malignancies (such as breast cancer, colorectal cancer, and hepatocellular carcinoma) and is closely associated with poor patient prognosis, making it a potential prognostic biomarker and therapeutic target. Furthermore, soluble CD87 (suPAR) has been established as a novel biomarker reflecting immune activation status in chronic inflammatory and infectious diseases (such as sepsis, HIV, and tuberculosis), capable of predicting disease progression and patient outcomes.

Immunohistochemistry
IHC shows positive staining in paraffin-embedded human liver. Anti-uPAR/CD87 antibody was used at 1/500 dilution, followed by a HRP Polymer for Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human lung. Anti-uPAR/CD87 antibody was used at 1/500 dilution, followed by a HRP Polymer for Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human spleen. Anti-uPAR/CD87 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

Immunocytochemistry
ICC analysis of U-937 cells treated with TPA (200nM, 72hr) (top panel) and untreated U-937 cells (below panel). Anti- uPAR/CD87 antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
