Hello,
It takes my blue/white screen more than 48 hours to become blue (pBS
in XL-1 Blue), but after a long while the colonies become deep blue. We spread 100 l of 100 mM IPTG and 40 l of Bluo-Gal
(Sigma, 40 mg/ml) per 10 cm dish. Which factors influence color
development? Is it critical to dissolve X-gal in dimethylformamide?
Thanks
