Buy some standard full length lambda cI857 Sam7 methylated DNA from NEB 
and electroporate into suitable E.coli host. Screen for lysogen i.e. 
grows at 28C but not 42C.

Or buy in same DNA but find someone with a lambda packing kit, package, 
plate screen etc.

I love deadlines. I especially like the whooshing noise they make as
they go flying by.
