Ingia / Ingia

Prions were purified from scrapie-infected hamster brains and incubated for 24 hr at 65 degrees with 2 mM Zn2+ or 5 mM Mg2+; no loss of infectivity was observed. Bacteriophage M13, tobacco mosaic virus (TMV), potato virus X, and potato spindle tuber viroid were all inactivated by divalent metal ions

Purified scrapie prions resist inactivation by UV irradiation.

Ingia / Ingia

The development of effective purification protocols has permitted evaluation of the resistance of isolated scrapie prions to inactivation by UV irradiation at 254 nm. Prions were irradiated on ice with doses of UV light ranging up to 120,000 J/m2. UV dosimetry experiments, performed with

Viroids and prions.

Viroids are small "naked" infectious RNA molecules that are pathogens of higher plants. The potato spindle tuber viroid (PSTV) is composed of a covalently closed circular RNA molecule containing 359 ribonucleotides. The properties of PSTV were compared with those of the scrapie agent, which causes a

Ingia / Ingia

The researches of DIENER and co-workers and those of the SEMANCIK'S group, have recently established that some plant diseases, such as potato spindle tuber, citrus exocortis disease and chrysanthemum stunt, are caused by a new class of pathogens, named viroids. These are the smallest known agents
