L′IPTG est couramment utilisé dans les procédures de clonage nécessitant une induction de l′activité β-galactosidase. Il est utilisé en conjonction avec X-Gal ou Bluo-Gal dans la sélection par couleur bleue ou blanche des colonies bactériennes recombinantes dans lesquelles l′expression de l′opéron lac d′Escherichia coli est induite. L′IPTG fonctionne en se liant au répresseur lacI et en modifiant sa conformation, ce qui empêche la répression du gène lacZ qui encode la β-galactosidase.
Autres remarques
Analogue non métabolisable du galactose.

There are two known mRNA degradation pathways, 3' to 5' and 5' to 3'. We identified likely pathogenic variants in two genes involved in these two pathways in individuals with intellectual disability. In a large family with multiple branches, we

Effector proteins of innate immune systems recognize specific non-self epitopes. Tectonins are a family of β-propeller lectins conserved from bacteria to mammals that have been shown to bind bacterial lipopolysaccharide (LPS). We present experimental evidence that two Tectonins of fungal
Bacterial habitats, such as soil and the gut, are structured at the micrometer scale. Important aspects of microbial life in such spatial ecosystems are migration and colonization. Here we explore the colonization of a structured ecosystem by two neutrally labeled
Killed avian influenza virus (AIV) vaccines have been used to control H5N1 infections in countries where the virus is endemic. Distinguishing vaccinated from naturally infected birds (DIVA) in such situations however, has become a major challenge. Recently, we introduced the
Enterotoxigenic Escherichia coli produce various heat-labile and heat-stable enterotoxins. STb is a low molecular weight heat-resistant toxin responsible for diarrhea in farm animals, mainly young pigs. A previous study demonstrated that cells having internalized STb toxin induce epithelial barrier dysfunction
