Verfahren zur Herstellung von Matrizen-DNA aus veredelter pflanzlicher Nahrung, die sich zur Amplifizierung eines DNA-Bereichs durch das PCR-Verfahren eignet

摘要

Preparation of a template DNA (I) from a processed plant food (A) comprises extraction a crude DNA fraction and subjecting this to fractionation by poly(ethylene glycol) (PEG) precipitation and/or polyacrylamide gel electrophoresis (PAGE), where (A) has been subjected to treatment or milling at high temperature, treatment under high pressure, or fermentation, and optionally it has been defatted.
