Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Shipping Information Freeze-dried E. coli 1046
Comments This E. coli contains the pCRE1 plasmid and expresses the Cre recombinase from a lacZ promoter.  Insert-containing lambdaMGU2 (77367) cannot grow productively in this RecA- strain, so excised phagemid are recovered as ampR surviviors of phage infection.

Restriction digests of the clone give the following sizes (kb): EcoRI--3.9, 2.05; XmnI--3.1, 2.4, 0.45; HindIII--5.2, 0.75; BamHI--4.4, 1.55; EcoRI/PstI--3.5, 1.4, 0.7, 0.35.
