Thanks, Sergio, you're right. It's always the same mistake I make:
Everytime I approach the X-Gal bottle in the fridge, my intra-brain
molecular biology freak control center tells me to use IPTG instead... ;-) 

Thinking about it more profundly: has anyone ever tried if X-Gal can be
used instead of IPTG, too? Like IPTG, it's Gal fused to a (maybe not so
much, but larger) lipophilic residue, just a little more expensive,
