Does anyone have experience with IPTG going bad? My stock bottle of 1
molar doesn't seem to be capable of inducing protein expression anymore.
It has always been stored frozen and thawed only for use. I haven't had
this happen before but then again, I've had this bottle for about a year
Either the IPTG isn't working anymore or two independent clones have
decided not to make proteins for me at the same time.
