R. Missich et al., TRANSFORMATION OF BIFIDOBACTERIUM-LONGUM WITH PRM2, A CONSTRUCTED ESCHERICHIA-COLI B-LONGUM SHUTTLE VECTOR, Plasmid, 32(2), 1994, pp. 208-211
An Escherichia coli-Bifidobacterium longum shuttle vector, designated
pRM2, was constructed by cloning a B. longum plasmid and an enterococc
al spectinomycin resistance gene into a commercial E. coli vector. The
plasmid was successfully introduced into B. longum cells by electropo
ration and into E. coli cells by both electroporation and chemical tra
nsformation. (C) 1994 Academic Press, Inc,
