어류분리 Vibrio anguillarum 용혈소의 정제
Purification of Hemolysin from Vibrio anguillarum Isolated from Fish
초록
1. 어류에서 분리한 V. anguillarum KS410의 용혈소를 분리하여 배양 상등액, 황산암모늄 침전, DEAE-cellulose column chromatography, Sephadex G-200 gel 여과 등의 과정을 통하여 36배 정제하였고 최종 회수율은 2.3%였다. 2. 정제된 용혈소의 SDS-PAGE상의 전기영동 결과는 38 Kda의 분자량을 보유하였다. 3. 온도에 대한 정제 용혈소는 45
A marine microbe, Vibrio anguillarum was isolated from fish and studied for its concerning pathogenic substance of hemolysin. Purification of hemolysin was achieved by the procedure of ammonium sulfate precipitation from cul-ture filtrate, DEAE-cellulose chromatography, and G-200 gel filtration with 36 fold of purification and 2.3% yield. The molecular weight of the purified hemolysin was 38,000 dalton by SDS-PAGE. The purified hemolysin was stable at pH 6-9, below 45
