    We 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

Depositor Comments

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).
