A dual fluorescent multiprobe assay for prion protein genotyping in sheep
BACKGROUND Scrapie and BSE belong to a group of fatal, transmissible, neurodegenerative diseases called TSE. In order to minimize the risk of natural scrapie and presumed natural BSE in sheep, breeding programmes towards TSE resistance are conducted in many countries based on resistance rendering PRNP polymorphisms at codons 136 (A/V), 154 (R/H) and 171 (R/H/Q). Therefore, a reliable, fast and ...
متن کاملGenotyping of PRNP coding region for scrapie in Indian sheep
Prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative disease by an entirely novel mechanism. The conformational change in prion proteins results in a change from a predominantly α-helical protein to a β-sheet form, which causes scrapie in sheep and goat. The present study was carried out to identify polymorphisms of the prion protein gene (PrP) ...

متن کاملUltrasensitive detection of pathological prion protein aggregates by dual-color scanning for intensely fluorescent targets.
A definite diagnosis of prion diseases such as Creutzfeldt-Jakob disease (CJD) relies on the detection of pathological prion protein (PrP(Sc)). However, no test for PrP(Sc) in cerebrospinal fluid (CSF) has been available thus far. Based on a setup for confocal dual-color fluorescence correlation spectroscopy, a technique suitable for single molecule detection, we developed a highly sensitive de...
متن کاملVisualization of prion infection in transgenic mice expressing green fluorescent protein-tagged prion protein.
Tg(PrP-EGFP) mice express an enhanced green fluorescent protein (EGFP)-tagged version of the prion protein (PrP) that behaves like endogenous PrP in terms of its posttranslational processing, anatomical localization, and functional activity. In this study, we describe experiments in which Tg(PrP-EGFP) mice were inoculated intracerebrally with scrapie prions. Although PrP-EGFP was incapable of s...
