Re: [DIYbio] Looking for bacterial expression plasmid SalI KpnI

Well, the lux operon seems to be very difficult to PCR. We tried it several times with brand new phusion (proof-reading) polymerase. No amplification.

Then we tried with phire polymerase, it works after some modification.

Phire is not proof-reading, yet it makes only half the errors as Taq. So, to see if there are no point mutations (that destroy the function of a lux gene) we'd need a promoter that reads off the lux genes in E coli. Designing new pirmers again... I'm glad these finally worked, so a plasmid with T5 or someting (not induced or induced) would seem awesome..

If you're talking about money, it'd probably be cheaper to order it
altogether. Promoters aren't usually that large, although if you want a
*good* one you'd need a bit more length.
