Technical Note: A Rapid Pulsed-Field Gel Electrophoresis Method for Analysis of Bifidobacteria

Pulsed-field gel electrophoresis comparing the traditional and rapid protocols, digested with XbaI. M: Lambda molecular weight marker; lanes with “a” were performed with the traditional method, and lanes with “b” were performed with the rapid method; lanes 1a/b: Bifidobacterium breve ATCC 15698; lanes 2a/b: B. breve ATCC 15700; Lanes 3a/b: Bifidobacterium longum ATCC 15707; Lanes 4a/b: B. longum ATCC 15708; Lanes 5a/b: Bifidobacterium animalis ssp. lactis (commercial strain).
