Resource Information

Depositor Comments

An XbaI site was introduced at the beginning of GFP, see attached map for more details.

The protein is expressed from IPTG inducible promoter in pKEN vector. GFP is cloned as XbaI-PstI fragment into the polylinker; there is also NdeI site at the AUG that can be used.

Mut 3 is probably best for expression in bacteria.

Overexpression of GFP renders the cells osmosensitive. In the absence of IPTG, DH12 carrying the enclosed plasmids will lyse in LB. We recommend growing this plasmid in low salt LB (<5g/L NaCl); alternatively use E.coli strain that grossly overproduces lacI and totally shuts expression down.
