Abstract

Flounder is one of the major aquacultured fish and of an economically important item in Korean fisheries. Recently, there are trends of research worldwide that aim to analyze and characterize a whole genome or a whole proteome of interesting species. The data are utilized for the understanding and development of preventive and curative technologies for the serious diseases. However, there are very limited information of proteome for marine organisms, we optimized first the conditions for two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) with serum form a marine fish, flounder (Paralichthys olivaceus). A pre-treatment of serum and an optimization of protein concentration analyzed were surveyed for enhancing the separation for proteins. A statistical analysis was performed on the overall 1,820 protein spots to overcome the variability among individual fishes.

넙치의 혈청 단백질체를 연구하기 위해 본 연구에서는 이차원전기영동 분석 시의 기본조건을 확립하였다. 넙치의 혈청단백질을 이차원전기영동 법으로 분석하기 위해서는 TCA 침전을 이용하여 혈청 내에 고농도로 존재하는 이온물질을 제거하는 전처리과 정이 반드시 요구되었다. 또한 분석 단백질의 농도는 $30{\mu}g$이 적당하였다. 넙치 10개체의 혈청단백질을 이용하여 총 51회의 이차원전기영동을 수행한 결과 1,8207개의 단백질로 이루어진 넙치 혈청단백질 표준 지도를 작성할 수 있었다.
