Growth instructionsWe consider it wise to store plasmids bearing a sacB gene at -80 deg. and to assess the very suspension that will be stored to be sure that it is highly sensitive to sucrose, and, similarly, to test individual colonies from which a sacB-bearing plasmid will be derived to be certain that sacB has retained great sensitivity to sucrose.

sacB was derived from pUM24 (Ried, J. L., and A. Colimer Gene 57:239-246, 1987) and from pUCD800 (Gay, et al. 1985 J. Bacteriol. 164:918-921).
The streptomycin/spectinomycin determinant in pRL277 was derived from the omega cassette (Prentki, et al. Gene 103: 17-23 1991).
