General description

The uptake of methyl-β-D-thiogalactoside (TMG), lactose, and glucose is maintained by the phosphoenolpyruvate-dependent phosphotransferase system.

Application

Methyl-β-D-thiogalactoside has been used in a study to analyze inducers of the E.coli lac repressor system. It has also been used in a study that investigated the utilization of lactose by Streptococcus faecalis.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Although the inducible prokaryotic lac repressor system has been successfully adapted for control of gene expression in mammalian cells, little information is available on the pharmacokinetics of beta-galactoside inducers in mammalian cells for optimizing this system. These studies directly measure

In the presence of gratuitous inducers, the lac operon of Escherichia coli exhibits bistability. Most models in the literature assume that the inducer enters the cell via the carrier (permease), and exits by a diffusion-like process. The diffusive influx and
