Abstract

processo para a ligação seletiva de uma forma anormal agregativa de uma proteína, processo ou ensaio quanto à presença de uma forma agregativa anormal de uma proteína de uma amostra, e, agente de ligação. as formas agregativas infecciosas de proteínas, tais como prp, amilóide e tau, são ligadas seletivamente na presença da proteína de forma normal, empregando-se um agente de ligação poliônica, tal como sulfato de dextrano ou pentosano (aniônico), ou compostos de poliamina, tais como pdadmac (catiônico), sob condições de ligação seletiva, incluindo o uso de n-lauroil sarcosina em ph suavemente alcalino, e podem então ser ensaiadas.
