General description

Monoclonal Anti-endothelial cell protein C receptor (EPCR) (rat IgG2a isotype) is derived from the RCR379 hybridoma produced by the fusion of mouse SP2/0 myeloma cells and lymphatic cells isolated from the superficial inguinal lymph nodes from Wister rats immunized with human EPCR-positive RE-1 cells. Endothelial protein C receptor (EPCR), also known as activated protein C receptor (APC receptor), is a protein encoded by the PROCR gene in humans and is mapped to the locus 20q11.22. EPCR is a type 1 transmembrane glycoprotein containing two domains in the extracellular region that are homologous to the α1 and α2 domains of CD1/ major histocompatibility complex class 1 (MHC) class 1 molecules. It is expressed exclusively in endothelial cells and small vessels such as capillaries of the alveolar wall in the lung.

Specificity

Monoclonal Anti-Endothelial Cell Protein C Receptor (EPCR) recognizes human EPCR (49 kDa).

Immunogen

human EPCR-positive RE-1 cells.

Application

Monoclonal Anti-Endothelial Cell Protein C Receptor antibody produced in rat is suitable for flow cytometry at a concentration of 5-20μg/mL using HUVEC cells.
Monoclonal Anti-Endothelial Cell Protein C Receptor antibody produced in rat may be used in immunohistochemistry.

Biochem/physiol Actions

Endothelial protein C receptor (EPCR) also known as activated protein C receptor (APC receptor) is involved in regulation of the cytoprotective and anticoagulant pathways of protein C. EPCR is a member of the CD1/major histocompatibility complex superfamily and plays an important role in regulating the inflammatory response. It is also identified as an endothelial receptor for specific P. falciparum erythrocyte membrane protein 1 (PfEMP1) subtypes. EPCR is associated with an increased risk of venous thromboembolism (VTE).
The EPCR protein also performs other functions, like binding to proteinase. The complex then binds to macrophage 1 antigen (MAC-1) on activated neutrophils and inhibits their adhesion to activated endothelium

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For prolonged storage, freeze in working aliquots at −20 °C. Repeated freezing and thawing is not recom-mended. Storage in frost-free freezers is also not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
