Invitrogen™ CD87 (UPAR) Monoclonal Antibody (VIM5), PerCP-eFluor™ 710, eBioscience™

Beschreibung

Description: This VIM5 monoclonal antibody reacts with human CD87, a GPI-linked receptor for urokinase plasminogen activator (uPA). By sequestering uPA, CD87 is involved in the conversion of plasminogen to plasmin on the leading edge of migrating cells, a process critical for chemotaxis. CD87 is expressed on the surface of monocytes, dendritic cells, and on activated T and NK cells. Interestingly, in granulocytes, CD87 expressed in the cytoplasm and on the cell surface. Non-hematopoietic cells such as endothelial cells, keratinocytes, and fibroblasts, also express this receptor. Finally, CD87 plays a role in cell adhesion and migration, angiogenesis, and tumor metastasis. This monoclonal antibody has been reported to have neutralization activity. Applications Reported: This VIM5 antibody has been reported for use in flow cytometric analysis. Applications Tested: This VIM5 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.25 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please ma...

The urokinase-type plasminogen activator receptor is a key molecule in the regulation of cell-surface plasminogen activation and plays an important role in many normal as well as pathologic processes. The human PLAUR cDNA encodes 335 amino acids including a predicted signal peptide of 22 residues and a hydrophobic C-terminal portion. It produces a highly glycosylated protein of about 50 kD in monocytes where it is anchored to the plasma membrane by glycosyl-phosphatidylinositol linkage. PLAUR, also known as UPAR, is directly associated with the carbohydrate-binding domain of SELL in the membrane of neutrophils, an association analogous to that between PLAUR and beta-2 integrins. PLAUR-mediated calcium mobilization is SELL dependent. UPAR mRNA levels correlate with the invasive potential of endometrial carcinomas and show a 33-fold increase in UPAR mRNA levels in advanced clinical stage endometrial tumors compared with normal endometrial tissue. Furthermore, the increase in UPAR mRNA levels correlated linearly with the progression of disease stage. UPAR protein expressioin correlated positively with rate of recurrence and mortality in patients with endometrial cancer. UPAR appears to be a useful prognostic marker for advanced endometrial cancer.
