TI Detection of species specific epitopes of mouse and hamster prion proteins (PrPs) by anti-peptide antibodies

PT journal article

AB Antisera to four synthetic peptides containing the substitutions between mouse and hamster prion proteins (PrPs) were produced in rabbits. The synthetic peptides used represent two mouse (Mo-I: residues 100-115 and Mo-V: residues 199-208) and two hamster PrP subregion sequences (Ha-I: 101-116 and Ha-V: 200-209). All antisera reacted strongly with homologous peptides but either not at all or poorly with heterologous peptides in enzymelinked immunosorbent assay (ELISA). Antisera to Mo-I and Mo-V recognized mouse PrPsc but not hamster PrPsc in western blot analysis (WB) and ELISA. Antisera to Ha-I contain antibodies specific to hamster PrPsc. The results indicate that these regions of PrPsc constitute species-specific epitopes. In contrast to these antisera, the antiserum to Ha-V recognized neither hamster nor mouse PrPsc. In this study, we identified mouse subregion-V as a species-specific epitope.

IN Die Autoren stellten polyklonale Kaninchenantikörper gegen synthetische Peptide her. Diese Peptide entsprachen den Aminosäuren 100-115 bzw. 199-208 des Mausprionproteins und den Aminosäuren 101-116 bzw. 200-209 des Mausprionproteins. Im Western Blot erkannten die Mausantisera nur scrapieassoziiertes Mausprionprotein, die Antikörper gegen das Hamsterpeptid 101-116 erkannten spezifisch das scrapieassoziierte Hamsterprionprotein. Das Serum gegen das Hamsterpeptid 200-209 funktionierte im Western Blot mit scrapieassoziierten Prionproteinen nicht.
