Re: [DIYbio] Synthetic promoters

It cost nothing since they could not synthesize it. If I want it I may just PCR it up and clone it the old fashioned way.

I don't know much about how companies synthesize oligos so what was
the reason for the failure? Too high GC content and other stability

I know we did some custom synthesis by PCR for a client since they had
trouble getting the synthesis companies to create it. Maybe you have
to go down that road?

By the way, how much did it cost you for this promoter at Operon?
