Abstract

In this study, the effects of five extraction methods for raw and processed corns were compared with respect to the integrity, yields and quality of DNA extracted from them and the results were assessed by PCR analysis. From the comparison of five extraction methods, DNA integrity showed a similar pattern. Amounts of genomic DNA obtained from the five extraction methods varies from $0.25{\mu}g\;to\;234{\mu}g$ per 1 g sample. The DNA yield extracted with CTAB method and DNeasy Plant Maxi kit is greater than that obtained from other extraction methods. These results would be applicable for the selection of an adequate extraction method for specific samples.

본 연구는 일반적으로 사용되는 DNA 추출방법들에 대한 효율을 비교하기 위해 수행하였다. 원료 옥수수 및 이를 가공한 시료들로부터 DNA추출을 하였으며, 추출된 DNA의 형상, 농도 및 순도 측정 그리고 PCR 분석 결과를 비교하였다. 5가지 방법으로 옥수수의 DNA를 추출한 결과, 추출방법에 따른 DNA 형상의 차이가 거의 없는 것을 확인하였으나, 각각의 시료들로부터 추출된 DNA의 양은 시료 g당 $0.25{\mu}g$부터 $234.0{\mu}g$까지 매우 다양하게 나타났다. 5가지 방법으로 옥수수 시료들의 DNA를 추출한 결과, CTAB법과 DNeasy plant Maxi 키트를 이용한 DNA 추출방법이 높은 수율을 보였다.
