This antibody recognizes the scrapie-associated protease-resistant isoform (PrPsc) of ovine prion protein (PrP). The prion protein is encoded by the PrP gene and is constitutively expressed as the normal cellular isoform PrPc by many cell types. Clone 2G11 specifically recognizes the R151-R159 sequence and does not recognize the non-pathogenic PrPc form.
Pre-treat samples with trypsin at 37°C for 5 minutes followed by heat-mediated antigen retrieval using 10mM citrate buffer (pH6.0), followed by treatment of tissue sections in 98% formic acid for 30 minutes for optimal results.
Human prion protein (PrP), also known as PRNP, is a ubiquitously expressed GPI-anchored cell surface glycoprotein associating with lipid raft components and functioning as a signaling molecule. PrP plays a role in apoptosis in a cell context-dependent manner, is involved in proliferation of epithelial cells and in distribution of junction-associated proteins in human enterocytes. Conversion of this normal cellular prion protein (PrPc) into an abnormal conformer (PrPSc) is the crucial step associated with triggering the pathogenesis of the prion neurodegenerative disorders, such as the Creutzfeld-Jakob disease (CJD). Whereas PrPc is rich in alpha-helices, the PrPSc form has higher content of beta-sheets and is resistant to proteinase K.
