Growth in Bacteria
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 neomycin/kanamycin determinant in pRL278 was derived from cassette C.K3 (Elhai and Wolk CP, 1988, Gene 68: 119-138).
The polylinker came, in large part, from the plC20R polylinker (Marsh et al.. 1984 Gene 32: 481-485) and from a polylinker region of plasmid pJRD184 (Heusterspreute et al.. 1985 Gene 37: 299-304).
